Outline of Final Research Achievements

Inspired by natural enzymes, we assumed that the catalyst should have multi-nucler structure and proton dissociative sites to efficiently catalyze multi-electron transfer reactions. In this research project, we investigated penta-nuclear complexes with proton dissociative sites, and found the following two important results.
(I) We succeeded in developing a penta-iron complex that catalyzes water oxidation with the lower overpotential. (II) We successfully synthesized a penta-nuclear metal complex with a confined proton, and demonstrated kinetic proton dissociation from the complex.
