| Outline of Final Research Achievements |
This study focused on the design of photocatalysts with excellent multi-electron oxidation ability and light utilization efficiency, based on porous coordination polymers (PCPs) whose metal-oxo clusters and organic molecules can be arranged in an ordered and dense manner. In order to improve the multi-electron oxidation ability of the metal-oxo clusters, PCP photocatalysts have been modified with cobalt oxides. As a result, the obtained materials showed enhanced photocatalytic oxygen evolution activity. In addition, photo-functional materials realizing antenna effects and photocatalysts enabling efficient electron transfers have been developed by using the ordered framework of PCPs and designing the structure of metal-oxo clusters with precision, respectively.
