Outline of Final Research Achievements

In this research, we have investigated the development of novel molecular catalysts for electrochemical water oxidation based on multinuclear metal complexes. A novel multidentate ligand bearing dissociative protons has been designed and synthesized. A novel copper tetranuclear complex has been synthesized using the multidentate ligand and crystallographically characterized. Electrocatalytic activity of the tetranuclear copper complex for water oxidation has been evaluated, and it was found that the tetranuclear copper complex serves as an efficient and robust water oxidation catalyst. We have also synthesized and crystallographically characterize novel hetero-multinuclear metal complexes, and evaluated their catalytic activity.
