Outline Activities
My research interests focuses on the material chemistry and photochemistry, and organic materials for opt-electronic devices. I focus to study the new fundamental organic dyes using the synthetic method that are candidates for dye-sensitized photo catalytic water-splitting reaction system in order to improve the light absorption, durability, and hydrogen production rate. Also, we focus the synthesis of novel organic dye for photo voltaic, and organic semicondoctor.

Current and Past Project
  • In this research, we aim to synthesize the precursor that can form cyclacene skeleton and achieve the target cyclacene by the reaction that is stimulated by mild condition such heat and/or light energy instead of chemical reaction. When the norbornadiene skeleton was selected as the starting material for the targeted cyclacene skeleton, we succeeded in synthesizing a bromohexacene precursor, which is a planar extension structure of the cyclacene skeleton. However, it was difficult to synthesize a precursor with a small ring size by this method, so reaction with norbornadiene-2,3,5,6-tetradiene was tried, but the corresponding cyclacene precursor could not be synthesized. . In the future, it has become an issue to consider the synthesis of cyclacene skeleton by multistep reaction.
  • In this research, I focused on the iron complex structure of hydrogenase-producing enzyme hydrogenase, developed a new organic iron cocatalyst to replace platinum that mimics of hydrogenase hydrogen production centre, and incorporated water into the non-precious metal hybrid photocatalyst appropriately incorporated in photocatalyst, and demonstrate the usefulness of decomposing hydrogen production and a new iron-based co-catalyst that can be converted to platinum. I will conduct screening of iron complexes in the past and develop organic iron complex promoters, clarify their physical properties, and combine inorganic oxide and iron complex promoters to create a model for photocatalysts.
