Outline of Final Research Achievements |
This work focused on developing molecular adhesive which facilitates electron transport by selective connecting photocatalyst materials. We demonstrated connection of two-different photocatalyst particles by using cross coupling of molecules attached on the surface. In addition, co-modification of a molecular unit, which facilitates photoinduced electron transfer, into the hetero-photocatalyst assembly. It is expected to control electron transport within the inter-particle photocatalyst assembly toward development of efficient photocatalysis of artificial photosynthetic reactions.

Academic Significance and Societal Importance of the Research Achievements |
二酸化炭素還元や水分解水素製造など、持続可能社会の実現に向けて期待されている人工光合成型反応を効率よく機能するためには、天然の光合成が巧みに引き起こしている高効率な電子移動機構をシンプルに模倣し、人工系に組み込む必要がある。本研究の成果は、光合成複合体のように酸化と還元を機能する反応中心を電子伝達モジュールで複合化する人工系構築に向けた第一歩であり、今後複合体間電子伝達の制御を進めることで高効率な人工光合成反応の実現が期待できる。
