@We are interested in the function of gsurfaceh of metal oxides such as TiO2, MgO, CaO, Ta2O5, MoO3 and WO3 and their mixed oxides. Fundamental studies of catalysis as well as photoconductivity of these materials are being undertaken. Of particular interest is the catalytic removal of nitrogen oxides, acidity of metal oxides, and highly selective and stable semiconductor sensor for NOx and COx.

@"Catalyst" is the key technology for solving environmental and energy problems. Research activities in my laboratory are focused on design of the highly-functionalized "catalysts" for 1) utilization of natural resorces such as methane and propane as a source of hydrogen and synthesis gas, 2) acid and base reactions, 3) oxidation reactions using molecualr oxygen and hydrogen peroxide as environmentaly benign oxidants, and 4) utilaiztion of carbon dioxide.

@My group has been studying photochemical reactions of organic compounds in solution and on a surface.@The photochemical reactions provide not only useful methods in organic synthesis but also useful information about the factors controlling organic reactions.@@One of our projects is the study of photoreactions involving intramolecular hydrogen abstraction by the excited carbonyl group.@The hydrogen abstraction is very specific in that g-hydrogen involving asix-membered cyclic transition state greatly predominates over other possible modes.@The abstraction via medium-sized transition states is quite rare events in photochemistry of ketones.@We found the first example of photocyclization involving a medium-sized transition state almost 20 years ago (J. Chem. Soc., Chem. Commun., 1983, 395) and have been studying photoreactions involving remote-hydrogen transfer. Wealready found some factors controlling the photoreactions. We have been also studying the application of the reaction to the synthesis of compounds having biological activities. Photoreactions of organic molecules on a silica-gel surface are also one of our main projects. The surface can provide a two-dimensional environment for effecting and controlling photochemical processes. We studied photoreactions of benzoylcycloalkanones and alkyl aryl ketones on a silica-gel surface found the surface provides not only the ordered environment but also a possible field bringing out the latent reactivity of dispersed molecules (J. Phys. Org. Chem., 9, 677 (1996)) and a polar reaction medium that makes the energy difference between the lowest n,* and upper ,* triplets small and may cause the inversion of the nearby n,* and ,* triplets (J. Phys. Org. Chem., 13, 437 (2000)).

@We research on the novel organic reaction and organic synthesis. Our research theme is divided into the following groups: oxidation reaction for organic synthesis (using molecular oxygen and various reagents), development of synthetic organic reaction using metal, synthesis of anti-oxidative compounds (chemistry of lipid oxidation), synthetic organic reaction using ultrasound chemistry, structural determination and synthesis of naturally occurring bioactive compounds, synthesis of heterocyclic compounds, oxidation and organic synthesis using phenolic compounds.
Key words: Synthetic Organic Reaction, Oxidation and Synthesis of Phenolic Compounds, Anti-Oxidative Compounds, Ultrasound Chemistry, Heterocyclic Compounds, Liqid Oxidation.

Fullerene Chemistry

Akira SAITO's Lab. (M205) (HP)

@The early transition elements V(V), Mo(VI), and W(VI) are known to form various kinds of polyoxometalates. Inclusion of a wide variety of elements as heteroatoms gives the polyoxometalate chemistry broader aspects. Polyoxometalate ions are regarded as assemblies of MO6 octahedra of the addenda atoms. There are several typical structures known as Keggin, Dawson, or Anderson structures, each of which has a unique architectural conformation. Some ions are stable and found either in solution and in solid, but many are known only as solids. Up to now, no decisive explanations have been presented to the question why a particular assemblage of the ions are stable. Polyoxometalate ions are nearly ten times larger than simple ions. In aqueous solutions and in solids, how are they interacting with counter cations and water molecules to be stabilized ? We are trying to find answers to these very basic questions by applying thermodynamic approach to the equilibrium in aqueous solutions, and by X-ray structure analyses of the solid compounds.

@Materials such as metal, ceramics and polymer are one of the most important technologies supported industry. The several improved functions of material, that is, physically, chemically and mechanically properties (conductivity, magnetism, corrosion resistance, strength and so on) are demanded. The aim of our research is synthesis of matter using soft solution eeco-friendlyf process and applied it as novel functional materials (for example, antibacterial activity). We also investigated the crystallographic structure and compositional distribution in nanometer order related to the mechanism of function employed with electron microscope and X-ray diffraction.
Keywords: functionally materials, soft solution process, surface and interface

@We are interested in design and synthesis of small organic molecules that can self-assemble and recognize interior and/or exterior of biopolymers, such as proteins. Our research projects will focus on the questions to see if protein-protein interaction, which in many cases involves large protein surface, can be disrupted by 1) designed molecular assembly systems where metal complexes are used for the molecular alignment, and 2) hybrid-receptors that consist of multiple modules for the simultaneous recognition of the interior and exterior protein.@Peptidomimetics, metal complexes, and dendrimers are of interest as the building blocks for both rational and combinatorial approach towards the molecular design.
