Outline of Final Research Achievements

Natural photosynthesis is composed of highly efficient molecular systems for electron transfer reactions, using multi-electron storage. In this study, we could succeed in developing new photosynthetic molecular systems having multi-electron storage moieties, based on coordination compounds. These molecular devices were found to show efficient catalytic properties for photodriven hydrogen evolution from water. In addition, we could find new metal complexes promoting photochemical oxygen evolution from water with high catalytic efficiencies.
