Abstract

The Ru(II)-polypyridyl complexes [Ru(H₂L)(terpy)][PF₆]₂ (1) and [Bu₄N][Ru(H₂L)(NCS)₃] (2) (H₂L = 4'-(3,4-dihydroxyphenyl)-2,2':6',2'-terpyridine), in which H₂L is coordinated as a terpyridyl fragment with a catechol site pendant from the C4' position, adhere effectively to nanocrystalline TiO₂ (anatase) surfaces via the pendant catechol group; incident photon-to-current conversion efficiency values of up to 50% were obtained in their photocurrent action spectra, suggesting flint the catechol unit may be a convenient and effective anchoring group for attaching dyes to TiO₂-based photovoltaic cells.
