Outline of Final Research Achievements

This study focuses on the development of water-splitting molecular systems having electron transfer units as the mimic of highly efficient electron transfer systems in nature. As a result, we succeeded in developing a molecular system driving photochemical hydrogen evolution from water operated with a similar mechanism to that driven by natural photosynthesis. In addition, a highly efficient water oxidation catalyst, which is the important target to realize the artificial photosythesis, was also successfully developed. Furthermore, we realized a near-infrared-light-driven hydrogen evolution from water with the use of a triruthenium photosensitizer. Finally, we developed a biphasic photochemical hydrogen-evolving system by employing molecular catalysts developed in this study.
