Abstract

A new family of Ru-Hbpp dinuclear complexes containing the positively charged terpyridine derivative ligand 4-(-p-(pyridin-1-ylmethyl)phenyl)-2, 2′:6′,2′-terpyridine of general formula {[Ru(L1 +)]2(μ-bpp)(L-L)}m+ (L-L = μ-Cl, μ-acetato, or (H2O)2; m = 4 or 5) have been synthesized and fully characterized, both in the solid state (X-ray diffraction) and in solution (1D and 2D NMR spectroscopy, UV-vis spectroscopy and electrochemical techniques). New hybrid materials have been prepared by the electrostatic interaction of these complexes with several oxidatively rugged solid supports such as SiO2, FTO-TiO2 and FTO-Nafion®. These new hybrid materials were prepared and catalytically evaluated with regard to their capacity to chemically and electrochemically oxidize water to dioxygen. © 2014 The Royal Society of Chemistry.
