    Conspectus Compounds with polarization switching properties have a wide range of applications including ferroelectric memories, pyroelectric sensors, and piezoelectric actuators. Ferroelectric compounds are primarily focused owing to their ability to switch between two or more symmetry-equivalent polarization states. Besides ferroelectrics, numerous compounds with polar structures exhibit polarization changes in response to external stimuli such as temperature and pressure; however, such effects are normally too small to be considered in practical applications. Recently, we proposed a strategy to achieve polarization switching via electron transfer in polar crystals. The strategy consists of the synthesis of molecules exhibiting intramolecular electron transfer, combined with crystal engineering to align these molecules so that the molecular dipole moments are not canceled at the lattice level. Consequently, vectorial (or directional) electron transfer results in a significant polarization change comparable to what is found for conventional ferroelectrics. Chemically, since the functional motifs are molecules, operational parameters such as the working temperatures and polarization change can be fine-tuned by adjusting the energy levels of the electron donor and acceptor sites and their separation, which enables a more active control of polarization than ferroelectrics. From a physical perspective, the key difference between these systems and ferroelectrics is that the polarization switching occurs between symmetry inequivalent and nondegenerate polar states. As a direct result, they can be switched by various external stimuli other than electric fields, including temperature, magnetic fields, pressure, and light, owing to their different physical properties such as entropy, magnetization, volume, absorption, etc. Moreover, although thermally- and photoinduced ferroelectrics have been reported, they typically form domain structures with different polarization direction due to a symmetry-related degenerate ground state, causing macroscopic polarization to be largely canceled. In contrast, our compounds, which lack accessible symmetry equivalent states, can achieve a perfect polarization alignment without polarization domains upon temperature changes, photoirradiation, or magnetic field. In this Account, we discuss the synthesis of polarization switching compounds, i.e., dinuclear [CoGa], [FeCo], and [CrCo] complexes, via a chirality-assisted method. The thermally induced polarization switching behavior, or pyroelectric effect, is then explained, highlighting the large polarization change (2.9 μC cm-2) in the [CoGa] complex, which is comparable to the widely used infrared (IR) detector material, triglycine sulfate (TGS). We then discuss the optical polarization memory effect and photoenergy conversion properties, which are a consequence of the photoinduced valence tautomeric behavior with a long-lived photoinduced metastable state. Furthermore, a magnetoelectric effect in the [FeCo] complex is described. The change in polarization is, to the best of our knowledge, the largest one induced by a magnetic field in molecular compounds to date. Notably, the polarization changes induced by temperature variation, photoirradiation, and magnetic field were detected as an electric current without the need of an electric field because polarization domains are not formed, unlike ferroelectric materials.

  • Altered Mode of Structural Changes in Solid Solutions Leading to Dual Modulation: Spin Transition Temperatures and Steps

    Wu, YY; Xu, GY; Yan, ZH; Zhou, XY; Yang, FL; Dai, JW; Wu, SQ; Li, ZY; Sato, O

    The development of high-density information storage materials requires precise control of electron spin states. Multistep spin-crossover (SCO) materials with multiple stable spin states are prime candidates for this purpose. However, accurate control of the dynamic SCO behavior, including the dual dynamic modulation of the spin transition temperature (Tc) and transition steps, has been a significant hurdle. In this study, we propose a new two-dimensional SCO solid solution system, [FeIII(H0.5LI)2-2x(H0.5LCl)2x]·H2O, where H0.5LX (LX for short) denotes 5-X-2-hydroxybenzylidene-hydrazinecarbothioamide, with X being I or Cl and x ranging from 0 to 1. The proposed system exhibits a unique nonmonotonic variation in Tc with x, obtaining a minimum at x = 0.7, allowing fine-tuning of Tc across a 66 K range and control over transition steps from two steps to one step, accomplishing dual modulation. Single-crystal diffraction analysis and periodic density functional theory (DFT) calculations demonstrate that the doped ligand LCl modulates the FeIIIN2O2S2 ligand field with increasing doped LCl ligands during the HS → LS transition in solid solutions, enabling dual dynamic modulation of the Tc and the number of transition steps from two steps to one step through dynamic variation in the structural contraction modes (from b- and c-axis contraction to a-axis contraction). This study motivates the synthetic control of dynamic SCO solid solutions through the altered mode of structural contraction as a complementary route to adjust their SCO behavior.

    Switching electric polarization by external stimuli constitutes a technical foundation for various applications. Here, we reported the observation of polarization-switching behavior in an oxo-bridged mixed-valence complex [Fe3O(piv)6(py)3] (piv = pivalate, py = pyridine). Detailed variable-temperature Mössbauer spectral analyses unambiguously confirm the occurrence of an electron localization-delocalization transition between two inequivalent Fe sites. Given that the compound crystallizes in a polar space group, the change in the molecular dipole moments leads to a pyroelectric effect observed during this transition, indicating thermally induced polarization switching behavior. As the complex exhibits asymmetry in the valence-active sites and antiferromagnetic interaction between them, the possibility of magnetoelectric coupling in this compound is also discussed on the basis of the recent prediction of polarization switching through modulating the degree of electron delocalization by magnetic fields in the mixed-valence systems.

    As a remote and non-contact stimulus, light offers the potential for manipulating the polarization of ferroelectric materials without physical contact. However, in current research, the non-contact write-read (erase) process lacks direct observation through the stable current as output signal. To address this limitation, we investigated the photoinduced polarization switching capabilities of the cyanide-bridged compound [Fe2Co] using visible light, leading to the achievement of rewritable polarization. By subjecting [Fe2Co] crystals to alternating irradiation with 785 nm and 532 nm light, the polarization changes exhibited a distinct square wave pattern, confirming the reliability of the writing and erasing processes. Initialization involved exposing specific crystal units to 532 nm light for storing “1” or “0” information, while reading was accomplished by scanning the units with 785 nm light, resulting in brief current pulses for “1” states and no current signal for “0” states. This research unveils new possibilities for optical storage systems, paving the way for efficient and rewritable data storage and retrieval technologies, such as the next-generation memories.

    In this study, we investigated reversible intermolecular proton shifting (IPS) coupled with spin transition (ST) in a novel FeII complex. The host FeII complex and the guest carboxylic acid anion were connected by intermolecular hydrogen bonds (IHBs). We extended the intramolecular proton transfer coupled ST phenomenon to the intermolecular system. The dynamic phenomenon was confirmed by variable-temperature single-crystal X-ray diffraction, neutron crystallography, and infrared spectroscopy. The mechanism of IPS was further validated using density functional theory calculations. The discovery of IPS-coupled ST in crystalline molecular materials provides good insights into fundamental processes and promotes the design of novel multifunctional materials with tunable properties for various applications, such as optoelectronics, information storage, and molecular devices.

    Mechanically interlocked molecules (MIMs) including famous catenanes show switchable physical properties and attract continuous research interest due to their potential application in molecular devices. The advantages of using spin crossover (SCO) materials here are enormous, allowing for control through diverse stimuli and highly specific functions, and enabling the transfer of the internal dynamics of MIMs from solution to solid state, leading to macroscopic applications. Herein, we report the efficient self-assembly of catenated metal-organic frameworks (termed catena-MOFs) induced by stacking interactions, through the combination of rationally selected flexible and conjugated naphthalene diimide-based bis-pyridyl ligand (BPND), [MI(CN)2]− (M = Ag or Au) and Fe2+ in a one-step strategy. The obtained bimetallic Hofmann-type SCO-MOFs [FeII(BPND){Ag(CN)2}2]·3CHCl3 (1Ag) and [FeII(BPND{Au(CN)2}2]·2CHCl3·2H2O (1Au) possess a unique three-dimensional (3D) catena-MOF constructed from the polycatenation of two-dimensional (2D) layers with hxl topology. Both complexes undergo thermal- and light-induced SCO. Significantly, abnormal increases in the maximum emission intensity and dielectric constant can be detected simultaneously with the switching of spin states. This research opens up SCO-actuated bistable MIMs that afford dual functionality of coupled fluorescence emission and dielectricity.

    Polar compounds with switchable polarization properties are applicable in various devices such as ferroelectric memory and pyroelectric sensors. However, a strategy to prepare polar compounds has not been established. We report a rational synthesis of a polar CoGa crystal using chiral cth ligands (SS-cth and RR-cth, cth = 5,7,7,12,14,14-hexamethyl-1,4,8,11-tetraazacyclotetradecane). Both the original homo metal Co crystal and Ga crystal exhibit a centrosymmetric isostructure, where the dipole moment of metal complexes with the SS-cth ligand and those with the RR-cth ligand are canceled out. To obtain a polar compound, the Co valence tautomeric complex with SS-cth in the homo metal Co crystal is replaced with the Ga complex with SS-cth by mixing Co valence tautomeric complexes with RR-cth and Ga complexes with SS-cth. The CoGa crystal exhibits polarization switching between the pseudononpolar state at a low temperature and the polar state at a high temperature because only Co complexes exhibit changes in electric dipole moment due to metal-to-ligand charge transfer. Following the same strategy, the polarization-switchable CoZn complex was synthesized. The CoZn crystal exhibits polarization switching between the polar state at a low temperature and the pseudononpolar state at a high temperature, which is the opposite temperature dependence to that of the CoGa crystal. These results revealed that the polar crystal can be synthesized by design, using a chiral ligand. Moreover, our method allows for the control of temperature-dependent polarization changes, which contrasts with typical ferroelectric compounds, in which the polar ferroelectric phase typically occurs at low temperatures.

    The study of transition metal clusters exhibiting fast electron hopping or delocalization remains challenging, because intermetallic communications mediated through bridging ligands are normally weak. Herein, we report the synthesis of a nanosized complex, [Fe(Tp)(CN)3]8[Fe(H2O)(DMSO)]6 (abbreviated as [Fe14], Tp−, hydrotris(pyrazolyl)borate; DMSO, dimethyl sulfoxide), which has a fluctuating valence due to two mobile d-electrons in its atomic layer shell. The rate of electron transfer of [Fe14] complex demonstrates the Arrhenius-type temperature dependence in the nanosized spheric surface, wherein high-spin centers are ferromagnetically coupled, producing an S = 14 ground state. The electron-hopping rate at room temperature is faster than the time scale of Mössbauer measurements (<~10−8 s). Partial reduction of N-terminal high spin FeIII sites and electron mediation ability of CN ligands lead to the observation of both an extensive electron transfer and magnetic coupling properties in a precisely atomic layered shell structure of a nanosized [Fe14] complex.

    Materials demonstrating unusual large positive and negative thermal expansion are fascinating for their potential applications as high-precision microscale actuators and thermal expansion compensators for normal solids. However, manipulating molecular motion to execute huge thermal expansion of materials remains a formidable challenge. Here, we report a single-crystal Cu(II) complex exhibiting giant thermal expansion actuated by collective reorientation of imidazoliums. The circular molecular cations, which are rotationally disordered at a high temperature and statically ordered at a low temperature, demonstrate significant reorientation in the molecular planes. Such atypical molecular motion, revealed by variable-temperature single crystal X-ray diffraction and solid-state NMR analyses, drives an exceptionally large positive thermal expansion and a negative thermal expansion in a perpendicular direction of the crystal. The consequent large shape change (~10%) of bulk material, with remarkable durability, suggests that this complex is a strong candidate as a microscale thermal actuating material.

    An important technique to realize novel electron- A nd/or proton-based functionalities is to use a proton-electron coupling mechanism. When either a proton or electron is excited, the other one is modulated, producing synergistic functions. However, although compounds with proton-coupled electron transfer have been synthesized, crystalline molecular compounds that exhibit proton-transfer-coupled spin-transition (PCST) behavior have not been reported. Here, we report the first example of a PCST Fe(II) complex, wherein the proton lies on the N of hydrazone and pyridine moieties in the ligand at high-spin and low-spin Fe(II), respectively. When the Fe(II) complex is irradiated with light, intramolecular proton transfer occurs from pyridine to hydrazone in conjunction with the photoinduced spin transition via the PCST mechanism. Because the light-induced excited high-spin state is trapped at low temperatures in the Fe(II) complex- A phenomenon known as the light-induced excited-spin-state trapping effect-the light-induced proton-transfer state, wherein the proton lies on the N of hydrazone, is also trapped as a metastable state. The proton transfer was accomplished within 50 ps at 190 K. The bistable nature of the proton position, where the position can be switched by light irradiation, is useful for modulating proton-based functionalities in molecular devices.

  • Giant Near-Infrared Induced Polarization Change via a Long-Lived Hidden Phase of a Valence Tautomeric Complex

    Zheng, WW; Wu, SQ; Shui, QR; Kanegawa, S; Su, SQ; Sato, O

    JOURNAL OF THE AMERICAN CHEMICAL SOCIETY   147 ( 16 )   13953 - 13961   2025.4   （ ISSN:0002-7863 eISSN:1520-5126 ）

    Light-induced polarization change has attracted significant attention due to its rapid response and nondestructive nature, positioning it as a promising candidate for next-generation molecular storage devices and energy harvesting. However, achieving substantial photoconversion that results in giant polarization changes via a hidden phase under near-infrared light irradiation remains a formidable challenge. In this study, we successfully synthesized a novel [CrCo] complex with an enantiopure ligand. Unlike previously reported Co valence tautomeric (VT) complexes, this complex exhibits light-induced VT (LIVT) with nearly complete photoconversion ratio upon irradiation with a 1340 nm laser. Additionally, the molecules pack in the P21 polar space group with an optimized arrangement, leading to a giant NIR-induced polarization change (1.71 μC cm-2), which surpasses that of other nonferroelectric crystals. Importantly, electric measurements and single-crystal X-ray analysis after irradiation revealed that the induced polarization change is related to not only the directional electron transfer but also the displacement of anions, which render a distinct hidden metastable phase compared to the thermally approachable one. Moreover, pyroelectric measurement was first used to characterize relaxation kinetics after light irradiation.

    Macroscopic polarization switching achieved through directional electron transfer or spin crossover (SCO) has attracted considerable attention because of its potential applications in data storage devices, sensors, and energy converters. Here, by substituting the central metal and anion of a reported compound, [Fe(RR-cth)Co(SS-cth)(μ-dhbq)](AsF6)3, we obtained two dinuclear compounds that crystallize in the polar space group, P21, [Fe(RR-cth)Ga(SS-cth)(μ-dhbq)] (X)3 (X = AsF6 and ClO4). Among them, complex 1(AsF6)3 exhibited a two-step magnetic transition, including SCO behavior near 50 K and a gradual valence tautomerism (VT) behavior that occurred over a wide temperature range up to at least 250 K. The SCO behavior of complex 1(AsF6)3 can be triggered by changes in temperature or the application of magnetic fields, leading to a polarization change of approximately 0.5 μC cm−2. The transition entropy of 55.9 J K−1 mol−1 during the SCO process was obtained using the Clausius–Clapeyron equation. Contrarily, complex 1(ClO4)3 only exhibited gradual VT behavior from a low temperature to room temperature. Single-crystal X-ray diffraction, variable-temperature infrared spectroscopy, and pyroelectric measurements confirmed the gradual VT process that occurs over a wide temperature range in both complexes. This study broadens the range of polarization switching molecular systems by replacing the central metal and anion, thereby facilitating the development of multifunctional molecular materials.

    In general, flexible metal-organic frameworks (MOFs) change their structures via framework breathing in response to external stimuli (usually guest adsorption and desorption). Here, we show a dynamic coordination bond in a flexible MOF driving a thermo-induced diffuse phase transition occurring in a wide temperature range of 130–270 K (centered at ∼200 K), which enables the switching of magnetism and second-harmonic generation (SHG) responses. In specific, a solvent-free CoII-based flexible MOF Co2(TPY)2(BPTC) (1), bearing biphenyl-3,3′,5,5′-tetracarboxylic acid (H4BPTC) and 2,2′:6′,2″-terpyridine (TPY) ligands, exhibits a reversible thermo-responsive coordination-mode switching between five- and six-fold. This dynamic bond results in the reversible transformation between a distorted polar framework and a regular nonpolar framework, and therefore leads to the subtle change of the magnetic property and substantial change of the nonlinear optical property of 1.

    Materials that exhibit polarization switching induced by directional charge transfer under external stimuli have garnered significant interest due to their high switching rates and potential applications. Nonetheless, most of these crystals contain solvents or counter ions, and their effects during measurement or calculations are far from trivial. Therefore, synthesizing a solvent-free and neutral complex exhibiting polarization switching is highly desirable. Herein, we successfully observed directional charge transfer-induced electronic pyroelectricity in a solvent-free neutral cobalt complex, namely, Co(teeda)(3,6-dbq)2 (teeda = N,N,N′,N′-tetraethylethane-1,2-diamine and 3,6-dbq = 3,6-di-tert-butylcatecholate or 3,6-di-tert-butylsemiquinonate). The charge transfer property was confirmed by magnetometry, infrared and UV-vis-NIR spectroscopy, and single-crystal X-ray diffraction (SCXRD) measurements. Furthermore, pyroelectric current was observed during the valence tautomerism (VT) process. Theoretical calculations demonstrated that polarization switching mainly originates from the charge transfer. These results indicate that Co(teeda)(3,6-dbq)2 is a promising candidate for exploring new VT compounds that exhibit polarization switching.

    Organic vapochromic materials which undergo a drastic change in their photophysical properties upon exposure to vapors or gases are attracting growing scientific attention because of their low price and wide range of possible applications. In this work, luminescence vapochromism of carbazole-pyridinium-based organic salts with a general structure of (CzPy)X (CzPy+=2,3-di(9H-carbazol-9-yl)pyridinium ion; X=Cl, Br or I) is reported. It was found that (CzPy)X compounds form J-aggregates, which rearranged back to monomeric form upon exposure to methanol, ethanol, acetone, and water vapors. In contrast, acetonitrile was found to promote the J-aggregation in (CzPy)X compounds by occupying the voids in their crystal lattice and pushing cations closer together. It was further demonstrated that the efficiency of J-aggregation in (CzPy)X compounds depends on the size of the anion, which was employed to realize dynamic luminescence vapochromism, with vapochromic response times ranging from a couple of minutes in (CzPy)Cl to more than an hour in (CzPy)I. In addition, (CzPy)X compounds exhibited high melting points of about 250 °C and excellent thermal stability. (CzPy)Cl and (CzPy)Br have also shown good photoluminescence quantum yields at room temperature in a solid state.

    The change of fluorescence emission manipulated by spin state transition attracts considerable attention owing to its potential applications in magneto-optical switching devices. Herein, we report two two-dimensional (2D) Hofmann-type spin crossover (SCO) metal-organic frameworks (MOFs) [FeII(PNI)2{AgI(CN)2}2]·CHCl3 (3Ag·CHCl3) and [FeII(PNI)2{AuI(CN)2}2]·CHCl3 (3Au·CHCl3) based on the fluorescent ligand N-(4-pyridylmethyl)-1,8-naphthalimide (PNI). Both complexes exhibit interesting SCO behaviors switched by guest solvent molecules, namely three-step transitions for the solvated complexes and complete one-step hysteretic SCO for the desolvated ones, verified by temperature-dependent magnetic susceptibility measurements, Mossbauer spectra, structural analyses, and differential scanning calorimetry measurements. Correspondingly, temperature-dependent fluorescence spectra exhibit double peaks (monomer and excimer emission) with both emission peaks change consistent with the change in SCO properties during the solvent molecule removal. In this study, we integrated guest-responsive SCO behavior into MOFs to manipulate the multistability of spin state and fluorescence switching, providing a rational strategy for the development of stimuli-responsive multifunctional materials.

However, the development of such materials is still infrequent and challenging. Here, a cyano-bridged square Prussian blue complex that exhibits a thermally induced four-step electron transfer coupled spin transition (ETCST) is reported. The magnetic and spectroscopic analyses confirm this multi-step transition. Variable-temperature infrared spectrum suggested the electronic structures in each phase and a four-step transition model is proposed.

    Organic photoresponsive materials, which change their physical properties upon irradiation with light, are attracting tremendous scientific attention, as they offer a flexible and sustainable platform for developing various optoelectronic devices. In this work, photoinduced magnetization switching in two carbazole-functionalized organic molecules, (9H-carbazol-9-yl)(4-chlorophenyl)methanone (ClPhCz) and (9H-carbazol-9-yl)(2,4-dichlorophenyl)methanone (DClPhCz) is reported for the first time. It was found that stabilization of the triplet excited state in those molecules is long enough for a net change in magnetic moment to be detected with a SQUID magnetometer. The change in magnetic moment upon excitation with a blue light laser was larger in ClPhCz, remaining high upon repeating the photoirradiation. In contrast, DClPhCz exhibited a smaller magnetic response, which gradually decreased upon repeating the experiment.

Single-crystal X-ray analysis reveals that compound 1 is an isolated neutral mixed-valence {FeIII2FeII}n double-zigzag chain with each [FeIII(Tp)(CN)3]− unit connecting with two Fe(II) centres via two of its three CN− groups in the cis-positions, and two triazole groups from btb coordinated with Fe(II) ion in its axial positions. Single-crystal data obtained at different temperature together with magnetic data indicate that complex 1 exhibits thermal induced spin transition in the Fe(II) sites with T1/2 ≈ 165 K. Additionally, light-induced excited spin-state trapping (LIESST) of 1 was also observed at low temperature.

    Macroscopic polarization switching via directional electron transfer has attracted great attention owing to its potential application in data storage devices, sensors, and energy conversion. However, the acquisition of the desired polar crystals is still a huge challenge to realize polarization switching. Here, a heterometallic [CrCo] complex with an enantiopure ligand was successfully obtained by a stepwise synthetic route, which effectively avoids the contamination caused by the lack of recognition of chiral ligands. Both compound 1·sol and its desolvated form, 1, are packed in the polar P21 space group. These forms exhibit valence tautomerism to varying degrees and interconversion to each other through single-crystal-to-single-crystal transformation, which enables solvent-dependent polarization-switching behavior. Moreover, both forms show trapping of the photoinduced electron-transferred states upon light irradiation. These findings highlight the effectiveness of using enantiopure ligands in constructing polar crystals with versatile polarization-switching behavior.

    We have experimentally investigated the mechanism of the exchange bias in 2D van der Waals (vdW) ferromagnets by means of the anomalous Hall effect (AHE) together with the dynamical magnetization property. The temperature dependence of the AC susceptibility with its frequency response indicates a glassy transition of the magnetic property for the Te-rich FeGeTe vdW ferromagnet. We also found that the irreversible temperature dependence in the anomalous Hall voltage follows the de Almeida-Thouless line. Moreover, the freezing temperature of the spin-glass-like phase is found to correlate with the disappearance temperature of the exchange bias. These important signatures suggest that the emergence of magnetic exchange bias in the 2D van der Waals ferromagnets is induced by the presence of the spin-glass-like state in FeGeTe. The unprecedented insights gained from these findings shed light on the underlying principles governing exchange bias in vdW ferromagnets, contributing to the advancement of our understanding.

    Spin-crossover (SCO) materials exhibit remarkable potential as bistable switches in molecular devices. However, the spin transition temperatures (Tc) of known compounds are unable to cover the entire ambient temperature spectrum, largely limiting their practical utility. This study reports an exemplary two-dimensional SCO solid solution system, [FeIII(H0.5LCl)2-2x(H0.5LF)2x]·H2O (H0.5LX = 5-X-2-hydroxybenzylidene-hydrazinecarbothioamide, X = F or Cl, x = 0 to 1), in which the adjacent layers are adhered via hydrogen bonding. Notably, the Tc of this system can be fine-tuned across 90 K (227-316 K) in a linear manner by modulating the fraction x of the LF ligand. Elevating x results in strengthened hydrogen bonding between adjacent layers, which leads to enhanced intermolecular interactions between adjacent SCO molecules. Single-crystal diffraction analysis and periodic density functional theory calculations revealed that such a special kind of alteration in interlayer interactions strengthens the FeIIIN2O2S2 ligand field and corresponding SCO energy barrier, consequently resulting in increased Tc. This work provides a new pathway for tuning the Tc of SCO materials through delicate manipulation of molecular interactions, which could expand the application of bistable molecular solids to a much wider temperature regime.

    Light-induced polarization switchable molecular materials have attracted attention for decades owing to their potential remote manipulation and ultrafast responsiveness. Here we report a valence tautomeric (VT) complex with an enantiopure chiral ligand. By a suitable choice of counter anions, a significant improvement in photoconversion has been demonstrated, leading to novel photo-responsive polarization switching materials.

    With the discovery of elastic single crystals of coordination polymers, the existing models that explain the mechanical properties of crystals have proved insufficient. Herein, microfocused synchrotron radiation analyses at the atomic level revealed that an organic single crystal underwent bending deformation attained by rotation, and slippage of molecules to retain integrity under external stresses. This study provides a valuable model to explain the mechanical properties of elastic single crystals having one-dimensional structure.

    Light, a nondestructive and remotely controllable external stimulus, effectively triggers a variety of electron-transfer phenomena in metal complexes. One prime example includes using light in molecular cyanide-bridged [FeCo] bimetallic Prussian blue analogues, where it switches the system between the electron-transferred metastable state and the system's ground state. If this process is coupled to a ferroelectric-type phase transition, the generation and disappearance of macroscopic polarization, entirely under light control, become possible. In this research, we successfully executed a nonpolar-to-polar phase transition in a trinuclear cyanide-bridged [Fe2Co] complex crystal via directional electron transfer. Intriguingly, by exposing the crystal to the wavelength of light─785 nm─without any electric field─we can drive this ferroelectric phase transition to completely depolarize the crystal, during which a measurable electric current response can be detected. These discoveries signify an important step toward the realization of fully light-controlled ferroelectric memory devices.

  • Control of electronic polarization <i>via</i> charge ordering and electron transfer: electronic ferroelectrics and electronic pyroelectrics

    Ferroelectric, pyroelectric, and piezoelectric compounds whose electric polarization properties can be controlled by external stimuli such as electric field, temperature, and pressure have various applications, including ferroelectric memory materials, sensors, and thermal energy-conversion devices. Numerous polarization switching compounds, particularly molecular ferroelectrics and pyroelectrics, have been developed. In these materials, the polarization switching usually proceeds via ion displacement and reorientation of polar molecules, which are responsible for the change in ionic polarization and orientational polarization, respectively. Recently, the development of electronic ferroelectrics, in which the mechanism of polarization change is charge ordering and electron transfer, has attracted great attention. In this article, representative examples of electronic ferroelectrics are summarized, including (TMTTF)2X (TMTTF = tetramethyl-tetrathiafulvalene, X = anion), α-(BEDT-TTF)2I3 (BEDT-TTF = bis(ethylenedithio)-tetrathiafulvalene), TTF-CA (TTF = tetrathiafulvalene, CA = p-chloranil), and [(n-C3H7)4N][FeIIIFeII(dto)3] (dto = 1,2-dithiooxalate = C2O2S2). Furthermore, polarization switching materials using directional electron transfer in nonferroelectrics, the so-called electronic pyroelectrics, such as [(Cr(SS-cth))(Co(RR-cth))(μ-dhbq)](PF6)3 (dhbq = deprotonated 2,5-dihydroxy-1,4-benzoquinone, cth = 5,5,7,12,12,14-hexamethyl-1,4,8,11-tetraaza-cyclotetradecane), are introduced. Future prospects are also discussed, particularly the development of new properties in polarization switching through the manipulation of electronic polarization in electronic ferroelectrics and electronic pyroelectrics by taking advantage of the inherent properties of electrons.

    Multiple proton transfer (PT) controllable by external stimuli plays a crucial role in fundamental chemistry, biological activity, and material science. However, in crystalline systems, controlling multiple PT, which results in a distinct protonation state, remains challenging. In this study, we developed a novel tridentate ligand and iron(II) complex with a short hydrogen bond (HB) that exhibits a PT-coupled spin transition (PCST). Single-crystal X-ray and neutron diffraction measurements revealed that the positions of the two protons in the complex can be controlled by temperature and photoirradiation based on the thermal- and photoinduced PCST. The obtained results suggest that designing molecules that form short HBs is a promising approach for developing multiple PT systems in crystals.

    Molecular-based magnetoelectric materials are among the most promising materials for next-generation magnetoelectric memory devices. However, practical application of existing molecular systems has proven difficult largely because the polarization change is far lower than the practical threshold of the ME memory devices. Herein, we successfully obtained an [FeCo] dinuclear complex that exhibits a magnetic field-induced spin crossover process, resulting in a significant polarization change of 0.45 μC cm-2. Mössbauer spectroscopy and theoretical calculations suggest that the asymmetric structural change, coupled with electron redistribution, leads to the observed polarization change. Our approach provides a new strategy toward rationally enhancing the polarization change.

    To alleviate the energy and environmental crisis, in the last decades, energy harvesting by utilizing optical control has emerged as a promising solution. Here we report a polar crystal that exhibits photoenergy conversion and energy storage upon light irradiation. The polar crystal consists of dinuclear [CoGa] molecules, which are oriented in a uniform direction inside the crystal lattice. Irradiation with green light induces a directional intramolecular electron transfer from the ligand to a low-spin Co^III centre, and the resultant light-induced high-spin Co^II excited state is trapped at low temperature, realizing energy storage. Additionally, electric current release is observed during relaxation from the trapped light-induced metastable state to the ground state, because the intramolecular electron transfer in the relaxation process is accompanied with macroscopic polarization switching at the single-crystal level. It demonstrates that energy storage and conversion to electrical energy is realized in the [CoGa] crystals, which is different from typical polar pyroelectric compounds that exhibit the conversion of thermal energy into electricity.

    The application of single-crystal neutron diffraction (SCND) to observe proton-transfer phenomena in crystalline compounds exhibiting unusual protonation states or proton dynamics has garnered significant research interest in recent years. However, proton tautomerism, which results in different protonation states before and after proton transfer, has never been observed using the SCND technique. Thus, to observe the proton tautomerism phenomenon by SCND measurements, we developed an iron(ii) complex that forms a large crystal and exhibits a proton-transfer-coupled spin transition (PCST). The presence of the two types of proton tautomers was determined by conventional analysis of the proton position by X-ray crystallography, infrared spectroscopy, and density functional theory calculations. Finally, our results confirmed that proton tautomerism was successfully observed for the first time using variable-temperature SCND measurements.

    Luminescent spin crossover (SCO) materials have attracted significant interest owing to their potential applications in magneto-optical switches. However, the majority of previously reported FeII-based SCO complexes are adversely affected by fluorescence quenching in the solid-state. Here, we have constructed the first mononuclear FeII complex decorated with an aggregation-induced emission (AIE) luminophore (i.e., tetraphenylethylene) that exhibits synergistic SCO and fluorescence behavior. Intriguingly, we obtained two types of crystals in different solvent systems, both displaying distinct magnetic bistability and fluorescence properties. The fluorescence intensity was observed to track the magnetic susceptibility, which confirmed that SCO and solid-state fluorescence operate synergistically. We introduce a novel approach for the construction of luminescent SCO compounds using an AIEgen as a luminophore, which leads to fluorescence emission in the solid-state, thus allowing us to study the synergy between SCO and fluorescence.

    The crystallization of a complex having electron transfer properties in a polar space group can induce the polarization switching of a crystal in a specific direction, which is attractive for the development of sensors, memory devices, and capacitors. Unfortunately, the probability of crystallization in a polar space group is usually low. Noticing that enantiopure compounds crystallize in Sohncke space groups, this paper reports a strategy for the molecular design of non-ferroelectric polarization switching crystals based on the use of intramolecular electron transfer and chirality. In addition, this paper describes the synthesis of a mononuclear valence tautomeric (VT) cobalt complex bearing an enantiopure ligand. The introduction of enantiomer enables the crystallization of the complex in the polar space group (P21). The polarization of the crystals along the b-axis direction is not canceled out and the VT transition is accompanied by a change in the macroscopic polarization of the polar crystal. Polarization switching via electron transfer is realized at around room temperature.

    Using light as a local heat source to induce a temporary pyroelectric current is widely recognized as an effective way to control the polarization of crystalline materials. In contrast, harnessing light directly to modulate the polarization of a crystal via excitation of the electronic bands remains less explored. In this study, we report an FeII spin crossover crystal that exhibits photoinduced macroscopic polarization change upon excitation by green light. When the excited crystal relaxes to the ground state, the corresponding pyroelectric current can be detected. An analysis of the structures, magnetic properties and the Mössbauer and infrared spectra of the complex, supported by calculations, revealed that the polarization change is dictated by the directional relative movement of ions during the spin transition process. The spin transition and polarization change occur simultaneously in response to light stimulus, which demonstrates the enormous potential of polar spin crossover systems in the field of optoelectronic materials.

    Some cyanide-bridged complexes are known for exhibiting slow magnetic relaxation behavior in a light-induced metastable state. Herein, an unexpected reverse effect is observed for the first time in the S= (Formula presented.) {FeII LS-CoIII LS-FeIII LS} (HS=high spin, LS=low spin) ground state of a novel V-shaped trinuclear cyanide-bridged {Fe2Co} complex. In this complex, light-switchable iron-cobalt charge transfer with repeatable off/on switching of slow magnetic relaxation is discovered upon alternating laser irradiation at 785 and 560 nm. An important characteristic of the present compound is that the S= (Formula presented.) ground state exhibits slow magnetic relaxation before irradiation, whereas this is accelerated after irradiation. This is different from the typical behavior, where the light-induced metastable state exhibits slow magnetic relaxation.

    Two rhodamine 6G-based mononuclear dysprosium complexes, [Dy(LR)(LA)2](ClO4)3·Et2O·1.5MeOH·0.5H2O (1) and [Dy(LR)(H2O)4(MeCN)](ClO4)3·2H2O·MeCN (2) (LR = salicylaldehyde rhodamine 6G hydrazone, LA = 2-pyridylcarboxaldehyde benzoyl hydrazone), are synthesized, aiming at improving the magnetic behavior by modulating their coordination environment. Both complexes own one exclusive short Dy-Ophenoxy coordination bond as the predominant bond and exhibit single-molecule magnet behavior under zero dc field with the energy barrier (Ueff/kB) of 90 K (1) and 320 K (2) and apparent hysteresis at 1.9 K. The ab initio calculations indicate that the short Dy-Ophenoxy bond determines the direction of magnetic anisotropic axis for 1 and 2. The quantum tunneling of magnetization (QTM) between the ground Kramers doublets (KDs) in 1 cannot be neglected, leading to an experimental Ueff/kB much lower than the calculated energy of the first excited state (318.2 K). For 2, the stronger magnetic anisotropy and negligible QTM between the ground KDs guarantees that the energy barrier is close to the calculated energy of first KDs (320.8 K). On the other hand, the presence of ring-opened xanthene moiety makes complexes 1 and 2 in the solid state emit red light with emission bands of 645 and 658 nm, respectively.

    Reversible controlling and switching of magnetic bistability remains relatively difficult. Here, reversible on-off switching of a hysteretic spin transition in a CoII complex via a single-crystal to single-crystal (SC-SC) transformation during dehydration and rehydration was reported. Upon dehydration, a switching from a basically low spin state to an abrupt and hysteretic spin crossover (SCO) with broad hysteresis loops was achieved. Hysteretic and anisotropic crystal lattice expansion or contraction in the spin transition temperature range was also observed in the dehydrated complex. The magneto-structural relationship in this system was established on the basis of detailed structure analyses on both the hydrated and dehydrated examples over a wide range of temperatures. The elimination of guest internal pressure, the tuning of the supramolecular interactions, and the strong electron-lattice coupling should be responsible for the hysteretic SCO in the dehydrated complex.

    The ability to switch a molecule between different magnetic states is of considerable importance for the development of new molecular electronic devices. Desirable properties for such applications include a large-spin ground state with an electronic structure that can be controlled via external stimuli. Fe42 is a cyanide-bridged stellated cuboctahedron of mixed-valence Fe ions that exhibits an extraordinarily large S = 45 spin ground state. We have found that the spin ground state of Fe42 can be altered by controlling the humidity and temperature. Dehydration results in a 15 μB reduction of the saturation magnetization that can be partially recovered upon rehydration. The complementary use of UV-vis, IR, L2,3-edge X-ray absorption spectroscopy and X-ray magnetic circular dichroism is applied to uncover the mechanism for the observed dynamic behavior. It is identified that dehydration is concurrent with metal-to-metal electron transfer between Fe pairs via a cyanide πhybridization. Upon dehydration, electron transfer occurs from low-spin {FeII(Tp)(CN)3} sites to high-spin FeIII centers. The observed reduction in magnetization upon dehydration of Fe42 is inconsistent with a ferrimagnetic ground state and is proposed to originate from a change in zero-field splitting at electron-reduced high-spin sites.

    Two new complexes were constructed via the coordination of fluorophores with Fe(ii) ions to study the effects of ligand substituents on fluorescent-spin crossover (SCO) materials. Single-crystal structural determination suggests that the central iron(ii) of complexes 1-2 adopted an N 4 O 2 coordination configuration, chelated by two ligands L 1 or L 2 . The π⋯π stacking interaction between the π-conjugated xanthene groups of the adjacent ligands for complex 1 is apparently stronger than that for complex 2. Magnetic susceptibility measurements show that complex 1 is high spin, while complex 2 is diamagnetic at room temperature. Interestingly, the desolvated form 1-d of complex 1 exhibits SCO behavior (T c = 175 K) without hysteresis. Significantly, complex 1-d displays the correlation between the spin crossover and the fluorescence.

    A helicene compound called AIBTh, wherein two azulene units are fused with isobenzothiophene, has been prepared and characterized by spectroscopic and crystallographic methods. The enantiomers of AIBTh were resolved by HPLC, exhibiting stable optical activity. AIBTh showed two reversible oxidation and one irreversible reduction waves with a HOMO-LUMO gap of 2.07 eV. Upon one-electron oxidation of AIBTh, its air-stable cation radical was isolated and analyzed by EPR as well as X-ray crystallography. Based on the EPR spectrum, the crystal structure, and DFT calculation, it is suggested that favorable resonance structures including aromatic tropylium cation forms and wide delocalization of electronic spin are dominating in the electronic structure of the cation radical.

    Metal-to-metal charge transfer (MMCT) describes electron transfer between metal ions, to generate valence isomers with markedly different electronic configurations. In particular, MMCT changes the spin states of single-metal sites and the coupling interactions between them, while also changing the symmetry in charge distribution. The result is a drastic change in both magnetic and electric properties of the affected material. Moreover, MMCT causes significant variation in bond length and absorption spectra, and induces unusual thermal expansion and photochromic behavior. Thus, materials demonstrating MMCT in response to external stimuli are excellent candidates for switchable multifunctional devices with synergistic responses. In this Minireview, recent progress in utilizing MMCT units as actuators to tune magnetic, electric, thermal expansion, and photochromic properties in cyanide-bridged systems is highlighted, and emphasis is given to the remaining challenges and future perspectives in the field.

    Here, we use a pyridinecarbaldehyde rhodamine 6G hydrazone ligand (L) to synthesize an Fe(II) complex 1 for the search of new fluorescent-spin crossover (SCO) materials. Single-crystal structural determinations suggest that the Fe(II) ion is chelated by two ring-opened ligands (L-o) to form a FeN4O2 coordination environment, and intermolecular π - -π contacts of the xanthene groups connect the adjacent molecules to form a supramolecular one-dimensional chain. Magnetic susceptibility measurements on complex 1 show that three-step SCO takes place in the temperature range of 120-350 K, and its desolvated form 1-d exhibits SCO around room temperature (Tc↑ = 343 K and Tc↓ = 303 K) with a wide hysteresis loop of 40 K. Moreover, complex 1-d displays light-induced excited spin-state trapping phenomenon. Intriguingly, the fluorescence intensity of the maximum emission at 560 nm for complex 1-d displays discontinuous variation in the range of 250-400 K, indicative of the occurrence of synergetic fluorescence and SCO.

    Magnetic and dielectric properties have been tuned simultaneously by external stimuli with rapid and sensitive response, which is crucial to monitor the magnetic state via capacitive measurement. Herein, positive charged FeII ions were linked via negative charged [(Tp)FeIII(CN)3]− (Tp=hydrotris(pyrazolyl)borate) units to form a neutral chain. The spin-crossover (SCO) on FeII sites could be sensitively triggered via thermal treatment, light irradiation, and pressure. SCO switched the spin state of the FeII ions and antiferromagnetic interactions between FeIII and FeII ions, resulting in significant change in magnetization. Moreover, SCO induced rotation of negative charged [(Tp)FeIII(CN)3]− units, generating dielectric anomaly due to geometric change of charges distribution. This work provides a rational way to manipulate simultaneous variations in magnetic and dielectric properties utilizing SCO as an actuator to tune spin arrangement, magnetic coupling, and charge distribution.

The ionic-liquid electrolysis cell mounted on a SQUID magnetometer was examined under DC bias voltage up to 4.0 V by injecting the charge carriers electrochemically into the PB film. Electrochemical hole doping increased the Fe III /Fe II ratio in the PB film, resulting in a remarkable enhancement of magnetization accompanied by quasi-reversible electrochromism.

    It is an ongoing challenge to design and synthesize magnetic materials that undergo colossal thermal expansion and that possess potential applications as microscale or nanoscale actuators with magnetic functionality. A paramagnetic metallocyanate building block was used to construct a cyanide-bridged Fe-Co complex featuring both positive and negative colossal volumetric thermal-expansion behavior. A detailed study revealed that metal-to-metal charge transfer between 180 and 240 K induced a volumetric thermal expansion coefficient of 1498 MK−1 accompanied with hysteretic spin transition. Rotation of the magnetic building blocks induced change of π⋅⋅⋅π interactions, resulting in a negative volume expansion coefficient of −489 MK−1, and another hysteretic magnetic transition between 300 and 350 K. This work presents a strategy for incorporating both colossal positive and negative volumetric thermal expansion with shape and magnetic memory effects in a material.

    An octacoordinated Fe(II) complex, [FeII(dpphen)2](BF4)2·1.3H2O (1; dpphen = 2,9-bis(pyrazol-1-yl)-1,10-phenanthroline), with a pseudo-D2d-symmetric metal center has been synthesized. Magnetic, high-frequency/-field electron paramagnetic resonance (HF-EPR), and theoretical investigations reveal that 1 is characterized by uniaxial magnetic anisotropy with a negative axial zero-field splitting (ZFS) (D ≈ -6.0 cm-1) and a very small rhombic ZFS (E ≈ 0.04 cm-1). Under applied dc magnetic fields, complex 1 exhibits slow magnetic relaxation at low temperature. Fitting the relaxation time with the Arrhenius mode combining Orbach and tunneling terms affords a good fit to all the data and yields an effective energy barrier (17.0 cm-1) close to the energy gap between the ground state and the first excited state. The origin of the strong uniaxial magnetic anisotropy for 1 has been clearly understood from theoretical calculations. Our study suggests that high-coordinated compounds featuring a D2d-symmetric metal center are promising candidates for mononuclear single-molecule magnets.

    The development of magnetic molecules with long spin reversal/decoherence times highly depends on the understanding of relaxation behavior under different external conditions. Herein, a magnetic study on a RuIII complex (1) is presented. Detailed analysis of the relaxation time and the magneto-heat capacity data suggests that the resonant phonon trapping process dominates the magnetic relaxation in the crystalline sample of 1, slowing down the spin relaxation rate, as further confirmed by the measurements on a ground sample and frozen solution. Thus, it provides a rare example showing that 4d metal-centered mononuclear compounds without second-order anisotropy can display slow magnetic relaxation.

The pair of N,N′,O-tridentate N-[1-(pyridin-2-yl-κN)ethyl]pyridine-4-carbohydrazonate L ligands result in a cis-NiO2N4 octahedral coordination sphere for the metal ions. The asymmetric units consist of two half-molecules of the dicarboxylic acids, which are completed by crystallographic inversion symmetry. In the respective crystals, the 2,5-dichloroterephthalic acid (H2Cl2TPA, 1-Cl) molecules form zigzag hydrogen-bonded chains with the [Ni(L)2] molecules, with the hydrogen-bond distances in 1-Br slightly longer than those in 1-Cl. The packing is consolidated by aromatic π-π stacking between the dicarboxylic acid molecules and terminal pyridine rings in [Ni(L)2] and short halogen-halogen interactions are also observed. The qualitative prediction of the H-atom position from the C - N - C angles of the terminal pyridine rings in L and the C - O distances in the carboxyl groups show that 1-Cl and 1-Br are co-crystals rather than salts.

    Polarization-switching materials have a wide range of applications including memory and sensors. We developed new polarization-switching cobalt valence tautomeric complexes. The cobalt complexes crystalize in a polar structure and exhibit intramolecular electron transfer at approximately 190 K. They also exhibit photoinduced electron transfer and that the photoinduced metastable state is trapped at low temperatures. These results suggest that the cobalt complexes exhibit thermal- and photo-induced polarization switching, the mechanism of which is electron transfer between Co and ligand.

    原子価異性錯体とは金属配位子間電子移動により酸化状態が可逆にスイッチする錯体であり、酸化還元異性錯体とも呼ばれる。代表的なコバルト原子価異性錯体ではコバルトとカテコール間で電子移動が誘起される。原子価異性現象は電子移動を伴うため、異性化に伴い分子の有する双極子モーメントが変化する。本研究では原子価異性錯体の分子配向を制御することにより、温度変化で分極が可逆に反転する新物質を開発する。
