Development of Pd(0) catalyzed one-pot synthesis of indoles based on N-H bonds activation : Pd(0) catalyzed one-pot synthesis of the indoles, which involves the Sonogashira Coupling of o-N-tosylamide with terminal alkynes, followed by N-H bond insertion of alkynes, has been developed. The Pd catalyzed one-pot reaction is applied to the synthesis of the hetrocyclic compounds.

Development of new photoreaction using photoinduced electron transfer and its application : In connection with application of photoinduced electron transfer, we are currently working on (1) investigation of photochemical syntheses of indole derivatives, and (2) development of new photochemical synthetic methods for quinone imine dyes and their application.

Construction and application of novel pi-electron system : To develop novel pi-electron system for organic materials, we synthesized some novel donor/acceptor arrays with aromatic bisimide and N-contain aromatic units, and we measured their properties and self-assembly abilities.

Development of novel functional coordination compounds : I am working on development of new functional coordination compounds. Specially, I am interested in green oxidation processes in presence of sugar-conjugated fluorochlorin derivatives as new photosensitizers.

Syntheses and evaluation of structure–property relationships of functional metal complexes exhibiting unique electronic properties. : We are studying on the development of functional materials showing electrical, magnetic and dielectric properties and optical functional materials that convert photo-energy into electric or chemical energy, based on metal complexes.

Creation of unique complexes containing commodity organic molecule : The purpose of our study is to examine the syntheses, structures, and electronic structures of unique complexes containing commodity organic molecules. Natural plant dyes and animal dyes are used as ligands.

Development and high-pure synthesis of new solid-state inorganic materials with excellent optical and electrical properties : The purpose of our study is to examine the syntheses, structures, and electronic structures of unique complexes containing commodity organic molecules. Natural plant dyes and animal dyes are used as ligands.

IR super-resolution microscopy for biological samples : We have developed IR super-resolution microscope with a sub-micrometer spatial resolution by 2-color laser spectroscopy. By using this microscope, we can observe not only vibrational molecular images but also the molecular orientation and chirality images of biological samples.

Emergence of novel physical properties and functions of polymers based on control of the hierarchical structures : By external force such as heat and mechanical force, we aim to emerge novel physical properties and functions of polymers based on control of the hierarchical strucures and to reveal the structure-property relationship.

Transient absorption spectroscopy measures the changes in the absorbance of short-lived species generated by photo-irradiation, and gives us the information about molecular dynamic processes in materials or chemical compounds. Rate constants are also determined by measuring time-profiles of the concentration of excited molecules.

Development of new flow analysis : We develop flow injection analysis, sequential injection analysis, liquid chromatography, and capillary electrophoresis using new analytical reagents and novel separation materials.

Utilization of biopolymer as an environmental material : DNA can be purified from either salmon milts, which are generally discarded as waste around the world. In this laboratory, we have demonstrated the utilization of DNA as an environmental material. As a result, DNA could selectively accumulate the planar structure-containing harmful compounds, rare-earth and heavy metal ions, and formaldehyde.

Elucidation of Mechanism of Solid-Liquid Interfacial Reaction: One of the factors affecting migration behavior of elements in hydrosphere is "adsorption of dissolved species on mineral surface". In recent years, it has been reported that various reactions to the adsorbed species occur. I aim to elucidate the mechanism of the reaction.
