| Outline of Final Research Achievements |
A new series of proximal,proximal-[Ru2(tpy)2(L)XY]3+ (L = 5-phenyl-2,8- di(2-pyridyl)-1,9,10-anthyridine, X and Y = the other coordination sites; denoted as p,p-Ru2XY) were synthesized using photoisomerization of a mononuclear complex. Unusual and stoichiometric exchange of μ-Cl with μ-OH, as well as hydroxo and aquo ligands on X and Y sites of p,p-Ru2XY is demonstrated. The p,p-Ru2(OH)(OH2) complex works more efficiently for electrochemical water oxidation, compared with a similar mononuclear complex and dinuclear derivatives with μ-Cl or μ-OH, due to the contribution of O-O bond formation by intramolecular radical coupling of RuV(=O)-RuV(=O) derived from the aquo and hydroxo ligands.
