Title : Mechanism of water oxidation and reversible proton dissociation on aquo-bridge between Ru(II) centres on dinuclear complexes


The ruthenium(II) complexes with polypyridyl ligands have been extensively studied due to the unique photochemical and photophysical properties and known to work as water oxidation catalyst. We have already reported dinuclear ruthenium(II) complex chelated by 5-phenyl-2,8-di(2-pyridyl)-1,9,10-anthyridine, and it works as an efficient catalyst for water oxidation. Herein we report another type of dinuclear ruthenium(II) complex chelated by 2,7-bis(2-pyridyl)-1,8-diazaanthracene with rare bridge structure of µ-aquo, µ–hydroxo and µ-oxo. The activity of electrocatalytic water oxidation is compared with those having the anthyridine backbone structure.


Shunsuke Watabe received his master's degree from Niigata University in 2017. He went on to the Ph.D course of Graduate School of Science and Technology in Niigata University in the same year.
