Profile
Extensive efforts have been made thus far to develop some catalytically active multinuclar metal complexes in our group. In this context, multinuclar coordination compounds involved in the active centers of the so-called metalloenzymes must be viewed as related to many of our research projects. Apart from the relatively abundant transition metals often found in the active centers of the enzyms, we have been focusing the studies on complexes with heavier or precious metals, such as Pt, Rh, and Ru. Our recent studies involve the following topics: ●Syntheses of multinuclear metal complexes with unusual electronic structures, such as strong metal-metal interactions leading to unusual/amzing reactivities. ●Development of Photosynthetic molecular devices which generate molecular hydrogen from water upon irradiation of visible light, which may be replaced with soloar light. ●Studies on the solution properties of metal complexes, which give better understanding to the reacction mechanisms of them in their catalysis. ●Syntheses, X-ray structure analysis, and physical properties of one-dimensional platinum chain complexes, where the anisotropic properties, nonlinear optical properties, metallic conduction properties, solid-satate emission properties, sensor properties (such as vapochromic behaviors upon exposure to a certain solvent gas) are focused. ●Development of molecular sensor by use of metal center as the recognition site for the sensing. For instance, we are now interested in the development of hydrogen-sensing metal complexes. Here students learn how to synthesize the coordination compounds including those of the ligands to be used. They also have a variety of chances to learn how to characterize, how to measure, how to calculate, how to evaluate, and so on. A large variety of analytical techniques must be used to perform the research on coordination chemistry. Thus, we think we are analytical chemists at the same time.

    The performance of a water-soluble cobalt porphyrin ([{meso-tetra(4-sulfonatophenyl)porphyrinato}cobalt(III)], CoTPPS) as a catalyst for the photoreduction of CO2 in fully aqueous media has been investigated under visible light irradiation using [Ru(bpy)3]2+ as a photosensitizer and ascorbate as a sacrificial electron donor. CO is selectively produced (>82%) with high efficiency (926 TONCO; TONCO = turnover number for CO). Upon optimization, selectivities of at least 91% are achieved. Efficiencies up to 4000 TONCO and 2400 h–1 TOFCO (TOFCO = turnover frequency for CO) are reached at low catalyst loadings, albeit with loss in selectivity. This work successfully demonstrates the ability of CoTPPS to perform highly efficient photoreduction of CO2 in water while retaining its high selectivity for CO formation.

    Our DFT results demonstrate that hydrogen evolution from water catalyzed by a nickel pyradinedithiolate (dcpdt) molecular hydrogen evolution catalyst [NiII(dcpdt)2]2− proceeds via the formation of a square-planar nickel(II) hydride intermediate which is given by unprecedented structural transformation of a doubly reduced triply protonated species [NiII(dcpdtH2)(dcpdtH)]−, afforded as a result of two consecutive ligand-based reductions of [NiII(dcpdt)(dcpdtH)]− through proton-coupled electron transfer (PCET) pathways.

    Two new nickel dithiolate derivatives have been examined for their electrocatalytic activity for hydrogen evolution reaction (HER) in attempts to clarify whether the overpotential for HER can be tuned upon varying the ligand-centered reduction potential that triggers HER by the catalysts. We demonstrate the validity of this approach to achieve desirable tunability in the overpotential for HER.

  • Photocatalytic H2 Evolution using a Ru Chromophore tethered to Six Viologen Acceptors Reviewed International journal

    Language:English   Publishing type:Research paper (scientific journal)  

    A new photo‐charge‐separator (PCS) consisting of a Ru(bpy)32+ (bpy: 2,2'‐bipyridine) chromophore and six viologen (MV2+) acceptors, [Ru(bpyMV2)3]14+, is synthesised and its application in photocatalytic H2 evolution is reported. The present PCS possesses shorter linkers in connecting a Ru chromophore and MV2+ acceptors in comparison with our previous PCSs (Inorg. Chem. Front., 2016, 3, 671‐680) and shows consecutive photo‐driven electron transfer in the presence of a sacrificial electron donor (EDTA), leading to multi‐electron storage over the PCS. This behavior can also be coupled with catalytic H2 evolution by the presence of a colloidal Pt catalyst. More importantly, the present PCS exhibits much higher durability during the photolysis, which is attributed to the higher rate in catalytic process. The high durability is also attributed to its bulky framework preventing undesirable side reactions.

    A series of platinum(II)-L-glutamic acid dendrimer conjugates having the formula PtCl2(5,5′-Gn(OR)-2,2′-bipyridine); Gn (n = 0, 1, 2), have been synthesized by various amide bond formation methods. The dendrimer complexes were terminated as carboxylic acid (R = H) or methyloxy ester (R = Me). The complexes were characterized by mass spectrometry, elemental analysis, UV-vis, FTIR, 1H-, 13C NMR, 1H-TOCSY, HSQC. The G1(OH) complex aggregate in solution and solid state, giving rise to a rigid conformation for the glutmaic acid side chain. The G2(OH) exists in the “monomeric” form with several conformations for the glutamic acid side chains. Complexes terminated with carboxyl group (R = H) were active catalyst toward hydrogen gas (H2) production by photo-induced splitting of water. The turnover frequency (TOF) for the G1(OH) complex is 14.7 × 1015 s−1, and it exhibits a ∼ 2-fold enhancement in H2 production compared to the unmodified parent complex G0(OH) (TOF = 7×1015 s−1). While G2(OH) complex displayed a lower hydrogen activity (TOF = 3.8 × 1015 s−1) compared to G0(OH). The platinum-glutamic acid dendrimer conjugates showed a correlation between H2 evolution activity and their ability to form aggregates, which driven by the steric hindrance of the peptide residues in the vicinity of Pt-center.

    The structures of four types of supramolecular systems containing [Pt(SCN)4]2– molecular units have been characterized. [Mn(bipy)2Pt(SCN)4]2·2MeOH (1) and [Zn(bipy)2Pt(SCN)4]2·2MeOH (2) show cis-thiocyanato ligands bridging the PtII and MnII or ZnII ions, leading to a molecular square motif. [Zn(bipy)2Pt(SCN)4]2 (3) presents chains where trans-thiocyanato ligands bridge the ZnII and PtII ions. For 1–3, free thiocyanato ligands are coordinated to the PtII centers to complete the square-planar coordination. [Pb(bipy)2Pt(SCN)4]2 (4) reveals a two-dimensional sheet structure where all SCN ligands bridge the PbII and PtII ions. [Pb(terpy)Pt(SCN)4]2 (5) is similar to 3, with two bridging trans-SCN ligands and two that are coordinated only to the PtII centers. For all compounds, d–d luminescence is observed with band maxima at approximately 14600 cm–1 (690 nm). Spectra show characteristic shifts with pressure, indicative of either intramolecular or intermolecular effects, depending on the sign of the shift. The pressure-dependent shifts for 1–5 show rich variations. A well-documented shift to higher energy due to metal–ligand bond compression is observed for 5 and can be used as a basis for a comparison. Compounds 1–4 show a shift of Emax to lower energy with pressures below 10 kbar. A change in sign for the shift of Emax occurs at 20, 12, and 10 kbar for 1, 2, and 3, respectively. For 4, only a shift to lower energy is observed. Competing intra- and intermolecular effects lead to these variations.

    It is successfully shown that photocatalytic proton reduction to dihydrogen in the presence of a sacrificial electron donor, such as trimethylamine (TEA) and ascorbate, can be driven by compact sensitizer–catalyst dyads, that is, dithiolate-bridged [FeFe] hydrogenase models tethered to organic sensitizers, such as fluorenes and silafluorenes (1 a–4 a). The sensitizer–catalyst dyads 1 a–4 a show remarkable and promising catalytic activities as well as enhanced stabilities during photocatalysis performed under UV-light irradiation. The photocatalysis was carried out both in non-aqueous and aqueous media. The latter experiments were performed by solubilizing the photocatalysts within micelles formed by either sodium dodecyl sulfate (SDS) or cetyltrimethylammonium bromide (CTAB). In this study a turnover number of 539 (7 h) is achieved under optimized conditions, which corresponds to an exceptionally high turnover frequency of 77 h−1. Theoretical investigations as well as emission decay experiments were performed to understand the observed phenomena together with the mechanisms of photocatalytic H2 generation.

    Copper tetrasulfonatophthalocyanine (CuPcTS) is reported to serve as a catalyst for photochemical water oxidation via a radical coupling mechanism. Chloride greatly inhibits the water oxidation rate as a result of axial chloride binding to CuPcTS, preventing formation of the Cu oxyl or hydroxyl intermediate required for O−O bond formation.

    Interest in platinum-chain complexes arose from their unusual oxidation states and physical properties. Despite their compositional diversity, isolation of crystalline chains has remained challenging. Here we report a simple crystallization technique that yields a series of dimer-based 1D platinum chains. The colour of the Pt2+ compounds can be switched between yellow, orange and blue. Spontaneous oxidation in air is used to form black Pt 2.33+ needles. The loss of one electron per double salt results in a metallic dz2 state, as supported by quantum chemical calculations, and displays conductivity of 11 S cm-1 at room temperature. This behaviour may open up a new avenue for controllable platinum chemistry.

    Single-chromophore-driven single-electron-pumping processes leading to multi-electron transfer and storage are effectively promoted in natural photosynthesis, generating photocurrent at the molecular level. Moreover, these single-electron-pumping events are converted into double-electron-pumping events by releasing multiple plastoquinol molecules without releasing reactive semiquinone radicals, thereby enabling storage of two-electron-reduced molecules within the lipid bilayer constructing the thylakoid membrane. Here we report new unimolecular architectures that enable these highly sophisticated light-driven multi-electron transfer and storage processes. The photo-charge-separators (PCSs) reported herein possess a single Ru(bpy)32+ fragment with each bpy derivatized with four dicationic viologen acceptors, abbreviated as [RuII(bpy)32+-(MV2+)12]26+ (MV2+ is a viologen unit). These highly positively charged PCSs form stable ion pairs with anionic electron donors, enabling consecutive multi-electron transfer processes from the donors to the pendant viologen acceptors. The multiple transferred electrons are collected over twelve pendant viologen acceptors, leading to storage of 7-8 electrons per molecule. The resulting organic radicals show a strong preference to form diamagnetic π-dimers, which suppress reactive radical formation. These reducing equivalents can then be efficiently consumed in catalytic H2 evolution from water in the presence of a colloidal platinum catalyst.

    Three chloro(4′-(N-methylpyridinium)-2,2′:6′,2′′-terpyridine)platinum(ii) (abbreviated as PtL2+) derivatives tethered to a single alkyl viologen unit (-(CH2)n-CH2-N+C5H4-C5H4N+-CH3; abbreviated as -Cn-MV2+, where n = 1, 3, and 4), i.e., PtL2+-Cn-MV2+, have been synthesized and investigated in detail. It is shown that the turnover number (TON) for the photocatalytic H2 evolution from water in the presence of a sacrificial electron donor EDTA (ethylenediaminetetraacetic acid disodium salt) is dramatically improved by the attachment of a single alkyl MV2+ unit (TON = 21.5-25.2, 12 h). Spectrophotometric studies reveal that the photoirradiation of PtL2+-Cn-MV2+ in the presence of EDTA initially leads to the formation of a 1-electron-reduced species, and then to a 2-electron-reduced species, where reductive quenching of a photoexcited species is a major path to the reduced photoproduct in each step. Electrochemical studies show that two consecutive 1-electron reductions at the PtL2+ unit are nearly overlapped with the corresponding reductions at the MV2+ unit. The 1-electron-reduced species can be thus expressed as either PtL+-Cn-MV2+ or PtL2+-Cn-MV+, while the 2-electron-reduced one as PtL+-Cn-MV+. Moreover, the latter products behave as stacked species involving three types of π-dimer sites, (PtL+)2, (MV+)2, and (PtL+)(MV+), and do not drive thermal H2 evolution according to the reaction: PtL+-Cn-MV+ + 2H+ → PtL2+-Cn-MV2+ + H2. The H2 evolution from water photocatalyzed by PtL2+-Cn-MV2+ has been found to occur via formation of 3-electron-reduced species; PtL+-Cn-MV+ + EDTA + hν → PtL0-Cn-MV+ (or PtL+-Cn-MV0) + EDTA(ox), and PtL0-Cn-MV+ (or PtL+-Cn-MV0) + 2H+ → PtL+-Cn-MV2+ (or PtL2+-Cn-MV+) + H2.

    Over the past decade, our group has focused on the studies of transition-metal-based molecular systems relevant to the development of artificial photosynthetic molecular devices. The targets of our research involve the studies on (i) water oxidation catalysis in order to uptake protons and electrons required for fuels generation, (ii) catalytic water or CO2 reduction into sustainable fuels (i.e., H2, CO, etc.), (iii) artificial light-harvesting systems towards the effective charge separation and/or migration, and (iv) molecular- and instrumental-level chemical engineering by making hybrid molecular and/or heterogeneous systems using multiple key components. Deeper insights into the mechanism of reaction of interest are always greatly appreciated for the sake of inspiring the rational design strategies towards the more desirable/efficient systems in promoting all relevant processes. In this context, substantial efforts have been devoted to more carefully study the reaction kinetics and equilibria in solution that are relevant to each topic. Various spectrophotometric, electrochemical, and photochemical techniques have been adopted to better understand the mechanistic aspects relevant to all of our systems. Some of the reaction steps of interest are not observable by any experimental techniques, and must be discussed on the basis of our DFT results, which have also greatly helped us understand the mechanism of reactions. Importantly, one of our findings is that, in any catalysis, the reactivity of metal(s) can be rationally tuned by use of redox active ligands that are more or less hybridized with metal(s) in their orbitals. Such issues are often involved in our discussion. One of our interests has concentrated on the molecular Pt-catalyzed hydrogen evolution reactions and their application to fabricate photosensitizer-catalyst hybrid molecular devices [1-3]. Our recent kinetic and electrochemical studies evidence the formation of a hydridodiplatinum(II,III) intermediate when H2 evolution is catalyzed by a simple mononuclear Pt(bpy)Cl2 derivative, which is also rationalized by our DFT results. Our studies have also provided new aspects on photo-induced multi-charge separation [4], near-infrared-driven water reduction [5], water oxidation catalysis using various transition metal complexes [6,7], non-precious metal based H2 evolution catalysis [8], and photoelectrochemical cells for the overall water splitting [9].

    In order to achieve practically useful artificial photosynthetic devices, we still need to gain deeper knowledge and skills in handling the basic chemical reactions catalyzed or photocatalyzed by transition metal based molecular systems. Our studies involve new materials synthesis, structure analysis, reaction kinetics, electrocatalysis, photocatalysis, DFT calculations, and so on. The presentation will focus on our recent advancements in clarifying the mechanism of some important energy-related molecular catalysis, such as hydrogen evolution, oxygen evolution, and even carbon dioxide reduction. The development of hybrid molecular devices consisting of multiple molecular components will also be discussed.

    The chemistry of water oxidation and reduction has been extensively studied from many
    viewpoints due to their significant relevance to solve the problems arising from the global
    warming and the shortage of fossil fuels. For both processes, proton-coupled electron
    transfer (PCET) processes have been considered to play the central role in drastically
    lowering the activation barriers for the relevant elementally steps. In the past decades, our
    group has paid specific interest in clarifying the mechanisms of transition-metal-based
    molecular catalysis for both processes [1-6]. In this presentation, some PCET processes that
    govern the rate of catalytic water reduction to evolve dihydrogen from water are discussed.
    The figure shown below illustrates that transition-metal-catalyzed water reduction can be
    roughly considered to undergo through three different types of PCET-based ratedetermining
    steps. The first metal-centered model is the case where the anti-bonding orbital
    in the square planar complex like a Pt(II) system forms a hydridoplatinum(III) intermediate
    [1,2,5]. This path will was also shown to undergo via formation of a diplatinum(II,III)
    interemediate due to its favorable stabilization via the Pt-Pt bond formation. An exceptional
    case is a Co NHC catalyst, for which metal-centered PCET occurs upon reduction of Co(II)
    d
    7
    leading to protonation at a Co(I) d8
    system [4], implying that the dz2 filled orbital
    provides basicity strong enough to promote protonation at the metal center. Our recent
    studies also demonstrated some unique hydride forming paths in which ligand-based
    reductions coupled with protonation at the ligand geometries can lead to metal hydride
    intermediate species required to catalyze hydrogen evolution from water [5,6].

    Solar light driven water splitting into H2 and O2 has been considered as one the most important targets of research in order to solve global warming and shortage of fossil fuels. Our group has long been endeavoring to develop practically useful molecular systems that can be adopted in artificial photosynthetic devices driving solar light induced water splitting reactions. In this context, the following four major issues have been intensively tackled: (i) development of photosynthetic molecular devices driving photoreduction of water to H2, (ii) development of photosynthetic molecular devices driving photo-oxidation of water to O2, , (iii) development of efficient charge separation devices photochemically generating oxidizing and reducing equivalents, and (iv) evaluations of the TiO2/FTO photoanodes and photocathodes anchored with the above photosynthetic molecular devices. Projects (i) and (ii) also involve profound efforts to fabricate and evaluate the more highly efficient molecular catalysts for both water reduction and oxidation.
    In the presentation, our recent studies on both water oxidation and reduction will be discussed. One is focused on photoinduced water oxidation catalyzed by cobalt porphyrin derivatives.1 The other is focused on the development of molecular devices for photoinduced water reduction using platinum(II) complexes as catalysts for hydrogen evolution reaction.2-4 The latter involves our recent success in the development of multi-charge separation devices that are tethered to multiple acceptor moieties, derived from methyl viologen derivatives.4

Works

  • KenX2013

    Ken Sakai

    2023.10

     More details

    This program package was originally developed as a Graphical User Interface for Shelxl97. However, various multipurpose tools for structure development are implemented. Especially, initial structure development tasks for DFT calculations are largely supported. We do develop many of model structures using this program.
    It also involves some CIF utilities for publication (CifConv.exe), a tool generating crystallographic table with multiple columns (CrysTab.exe), and a tool to convert HKLF data by defining a transformation matrix (HKLConv.exe).

    KenX was greatly changed from the former versions. KenX2020 can be used to convert molecular structures to be handled in DFT calculation. It reads a cartesian coordinate file, allows deformation of structures, exports Gaussian Input Files, etc. The last Gaussian-com-file saving routine has been greatly improved from this version. You can prepare some standard input codes to be inserted into your creating input files, before saving.

    Bug Fix Report
    ### May 29, 2016 ### Naming Routine Error in Action when Applied Fixed.
    ### June 14, 2016 ### Distances and Angles Data Display Routine Revised.
    ### Sept 20, 2016 ### Bug Fixed for Coordinates Generation by the Shift Rountine.
    ### May 21, 2017 ### Some routines for Molecular Treatments for the structure development Revised.
    ### Oct 02, 2018 ### Translational structure moving events revised to enable a little smaller shift (fine tue of position can be done from this version).
    ### April 20, 2020 ### Remember Unselected. This is added to memorize the unselected part of atoms in a memory, which can be restored by the ReSelect button. This is used for make some rotations along the selected axes of interest in order to make various conformers in a logical way.
    ### April 20, 2020 ### The problems about the window tasks and display regions have been greatly solved.
    ### April 28, 2020 ### More options added; Align Vector, Remember Unselected, Reverse Selection. Moreover, the Locate Option has largely improved to make the user able to locate fragments stored in KenX/fragments folder. File saving routine for producing fragment files have also been added.
    ### May 8, 2020 ### The problem about the accessing folder memorizing strategy has been solved. Now, multiple KenX windows can momorize their individual accessing folder separately so that the individual task may be done much more effectively. The previous version had a problem of memorizing the accessing folder using a single path recording file within a KenX program folder.

    $$$ July 07, 2021 $$$ The hydrogen atom lable display error plus a trivial graphic display error upon the symmetry expansion process have been solved to disply them correctly. Especially, the H atom names (described by Brush.Style := bsBold in an unexpected error by the complier has been avoided by inserting Brush.Style := bsClear before all H-name descpription task treatments.

    ### October 11, 2023 ### The least-squares calculations on the individually defined planes in molecules or crystals can now be performed by simply clicking the atoms. The plane calculation results can be saved into an ASCII file to be imiported into Excel file for detailed examinations.

    2021.8

     More details

    Reading Gaussian03/09/16 Output files.
    1. Coverting Coordinates Files
    2. Picking up the SCF-Done Energies during the optimization, although there is no meaning in chemical viewpoints. However, this allows you to quickly monitor whether the optimization procedures are going ok or not. These energies can also be viewed graphically. Can extract the final atomic coordinates in a cartesian format and save them as a file for further use. Maximum and RMS Force together with Maximum and RMS Displacement during the optimization can now be graphically viewed.
    3. This tool can extract the final coordinates in Z-matrix format and save them in a Gaussian input format file in the Z-matrix format.
    4. This is a powerful tool now because it can automatically produce a report which can be utilized for supplementary materials preparation.
    5. Comparison of Multiple MO Energy Diagrams can be graphically viewed.
    6. Projected Density Of States can be plotted. This is useful for studying the density of states of metal clusters (requires PW to activate).
    7. MO Coefficients can be read but with the Log files generated using Pop=Full is required. After reading the Log file, the corresponding FCH file can be read to be replaced with the data in the FCH file (requires PW to activate).

     More details

    ESR Simulation Program (esr_simulator.exe). In this new version, simulation of ESR spectra for non-100%-abandance nuclei like Pt-195 (33.8%) can be simulated. This version also can deal with I=5/2 Mn and all other Nuclei, though all of them have not been implemented as yet. At present, only 1H, 2H, 14N, 15N, 55Mn, and 195Pt have been installed for our use. Those who need to add other nuclei can contact KS........

    Updated on 2017-06-04: Parameters saving routines added. Blank lines auto-deleting routines added.
    Updated on 2017-06-07: A routine adding an additional broad gaussian feature has been introduced. Moreover, the values with two decimals can now be defined for the coupling constants.
    Updated on 2017-06-13: Scroll Bars (Automatic) have been added.

     More details

    A stand-alone program simulating Isotope Patterns for the data analysis in Mass Spectrometry (WinMassSpec.exe). Since the older versions of the program (WinMass.exe) suffered from a bug, I made a completely revised version of the simulation program. Isotopic abundances data for almost all the well-known elements have now been implemented in 'Elem.txt' and 'abundances.txt'. If you need or would like to modify the basic numerical parameters concerning the abundances, you can easily do so by editting the files mentioned above.
