15. Junqiu Li, Shuqi Wu, Shengqun Su, Shinji Kanegawa, Osamu Sato, Manipulating Slow Magnetic Relaxation by Light in a Charge Transfer {Fe2Co} Complex, Chemistry - A European Journal, 10.1002/chem.202000154, 26, 15, 3259-3263, 2020.03, 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..

Mei Jiao Liu, Shu Qi Wu, Jia Xin Li, Yi Quan Zhang, Osamu Sato, Hui Zhong Kou, Structural Modulation of Fluorescent Rhodamine-Based Dysprosium(III) Single-Molecule Magnets, Inorganic chemistry, 10.1021/acs.inorgchem.9b03105, 59, 4, 2308-2315, 2020.02, 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..

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..

Zi Shuo Yao, Hanxi Guan, Yoshihito Shiota, Chun Ting He, Xiao Lei Wang, Shu Qi Wu, Xiaoyan Zheng, Sheng Qun Su, Kazunari Yoshizawa, Xueqian Kong, Osamu Sato, Jun Tao, Giant anisotropic thermal expansion actuated by thermodynamically assisted reorientation of imidazoliums in a single crystal, Nature communications, 10.1038/s41467-019-12833-y, 10, 4805, 2019.10, 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..
20. Takumi Nakanishi, Yuta Hori, Hiroyasu Sato, Shu Qi Wu, Atsushi Okazawa, Norimichi Kojima, Takashi Yamamoto, Yasuaki Einaga, Shinya Hayami, Yusuke Horie, Hajime Okajima, Akira Sakamoto, Yoshihito Shiota, Kazunari Yoshizawa, Osamu Sato, Observation of Proton Transfer Coupled Spin Transition and Trapping of Photoinduced Metastable Proton Transfer State in an Fe(II) Complex, Journal of the American Chemical Society, 10.1021/jacs.9b07204, 141, 36, 14384-14393, 2019.09, 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..
21. Dong Shao, Le Shi, Fu Xing Shen, Xiao Qin Wei, Osamu Sato, Xin Yi Wang, Reversible On-Off Switching of the Hysteretic Spin Crossover in a Cobalt(II) Complex via Crystal to Crystal Transformation, Inorganic chemistry, 10.1021/acs.inorgchem.9b01436, 58, 17, 11589-11598, 2019.09, 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..
22. Michael L. Baker, Shu Qi Wu, Soonchul Kang, Satoshi Matsuzawa, Marie Anne Arrio, Yasuo Narumi, Takumi Kihara, Tetsuya Nakamura, Yoshinori Kotani, Osamu Sato, Hiroyuki Nojiri, Electron-Transfer Activity in a Cyanide-Bridged Fe42 Nanomagnet, Inorganic chemistry, 10.1021/acs.inorgchem.9b01216, 58, 15, 10160-10166, 2019.08, 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..
23. Juan Yuan, Mei Jiao Liu, Shu Qi Wu, Xin Zhu, Nan Zhang, Osamu Sato, Hui Zhong Kou, Substituent effects on the fluorescent spin-crossover Fe(ii) complexes of rhodamine 6G hydrazones, Inorganic Chemistry Frontiers, 10.1039/c9qi00111e, 6, 5, 1170-1176, 2019.05, 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..
24. Masahiro Narita, Takaaki Teraoka, Toshihiro Murafuji, Yoshihito Shiota, Kazunari Yoshizawa, Shigeki Mori, Hidemitsu Uno, Shinji Kanegawa, Osamu Sato, Kenta Goto, Fumito Tani, An azulene-based chiral helicene and its air-stable cation radical, Bulletin of the Chemical Society of Japan, 10.1246/bcsj.20190219, 92, 11, 1867-1873, 2019.01, 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..
25. Yin Shan Meng, Osamu Sato, Tao Liu, Manipulating Metal-to-Metal Charge Transfer for Materials with Switchable Functionality, Angewandte Chemie - International Edition, 10.1002/anie.201804557, 57, 38, 12216-12226, 2018.09, 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..
26. Juan Yuan, Shu Qi Wu, Mei Jiao Liu, Osamu Sato, Hui Zhong Kou, Rhodamine 6G-Labeled Pyridyl Aroylhydrazone Fe(II) Complex Exhibiting Synergetic Spin Crossover and Fluorescence, Journal of the American Chemical Society, 10.1021/jacs.8b00103, 140, 30, 9426-9433, 2018.08, 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..
27. Hui Zheng, Yin Shan Meng, Guang Li Zhou, Chun Ying Duan, Osamu Sato, Shinya Hayami, Yi Luo, Tao Liu, Simultaneous Modulation of Magnetic and Dielectric Transition via Spin-Crossover-Tuned Spin Arrangement and Charge Distribution, Angewandte Chemie - International Edition, 10.1002/anie.201802774, 57, 28, 8468-8472, 2018.07, 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..
28. Mariko Noguchi, Motohiro Nakano, Soonchul Kang, Osamu Sato, Shu Seki, Paramagnetism enhancement by in situ electrochemical hole doping into a Prussian Blue thin film, Materials Chemistry Frontiers, 10.1039/c7qm00615b, 2, 5, 1004-1008, 2018.01, A Prussian Blue (PB) film formed on an indium tin oxide substrate was incorporated in an electrolysis cell with an ionic-liquid midlayer (N,N-diethyl-N-methyl-N-(2-methoxyethyl)ammonium bis(trifluoromethanesulfonyl)imide) as an electrolyte. 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..
29. You Gui Huang, Shu Qi Wu, Wei Hua Deng, Gang Xu, Fa Lu Hu, Jonathan P. Hill, Wei Wei, Sheng Qun Su, Lok Kumar Shrestha, Osamu Sato, Ming Yan Wu, Mao Chun Hong, Katsuhiko Ariga, Selective CO2 Capture and High Proton Conductivity of a Functional Star-of-David Catenane Metal–Organic Framework, Advanced Materials, 10.1002/adma.201703301, 29, 42, 2017.11, Network structures based on Star-of-David catenanes with multiple superior functionalities have been so far elusive, although numerous topologically interesting networks are synthesized. Here, a metal–organic framework featuring fused Star-of-David catenanes is reported. Two triangular metallacycles with opposite handedness are triply intertwined forming a Star-of-David catenane. Each catenane fuses with its six neighbors to generate a porous twofold intercatenated gyroid framework. The compound possesses exceptional stability and exhibits multiple functionalities including highly selective CO2 capture, high proton conductivity, and coexistence of slow magnetic relaxation and long-range ordering..
30. Ji Xiang Hu, Yang Xu, Yin Shan Meng, Liang Zhao, Shinya Hayami, Osamu Sato, Tao Liu, A Material Showing Colossal Positive and Negative Volumetric Thermal Expansion with Hysteretic Magnetic Transition, Angewandte Chemie - International Edition, 10.1002/anie.201707258, 56, 42, 13052-13055, 2017.10, 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..
31. Guo Ling Li, Shu Qi Wu, Li Fang Zhang, Zhenxing Wang, Zhong Wen Ouyang, Zhong Hai Ni, Sheng Qun Su, Zi Shuo Yao, Jun Qiu Li, Osamu Sato, Field-Induced Slow Magnetic Relaxation in an Octacoordinated Fe(II) Complex with Pseudo-D2d Symmetry
Magnetic, HF-EPR, and Theoretical Investigations, Inorganic Chemistry, 10.1021/acs.inorgchem.7b00765, 56, 14, 8018-8025, 2017.07, 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..
32. Shu Qi Wu, Yuji Miyazaki, Motohiro Nakano, Sheng Qun Su, Zi Shuo Yao, Hui Zhong Kou, Osamu Sato, Slow Magnetic Relaxation in a Mononuclear Ruthenium(III) Complex, Chemistry - A European Journal, 10.1002/chem.201702047, 23, 42, 10028-10033, 2017.07, 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..

In the complex, [Co(C20H14N4S)(H2O)2]2+ cation, the tetradentate 6,6′-sulfanediylbis(2,2′-bipyridine) ligand coordinates to the CoII cation in the equatorial positions, while two water molecules occupy the axial positions, forming a compressed octahedral CoN4O2 coordination sphere.

Takumi Nakanishi, Osamu Sato, Crystal structures of two nickel compounds comprising neutral NiII hydrazone complexes and dicarboxylic acids, Acta Crystallographica Section E: Crystallographic Communications, 10.1107/S2056989016020326, 73, 103-106, 2017.01, Two isostructural NiII compounds, bis{N-[1-(pyridin-2-yl-κN)ethylidene]pyridine-4-carbohydrazonato-κ2 N′,O}nickel(II)-2,5-dichloroterephthalic acid (1/1), [Ni(C13H11N4O)2](C8H4Cl2O4), and bis{N-[1-(pyridin-2-yl-κN)ethylidene]pyridine-4-carbohydrazonato-κ2 N′,O}nickel(II)-2,5-dibromoterephthalic acid (1/1), [Ni(C13H11N4O)2](C8H4Br2O4), were synthesized and their crystal structures determined. 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..
