Abstract

A new ruthenium (II) complex, [Ru(terpy-Ph-PO₃H₂)₂]2⁺ (where terpy-Ph-PO₃H₂ = 4'-p-phosphonophenyl)-2 ,2':6,2''-terpyridine), has been synthesized for the photosensitization of anatase TiO₂ towards the visible spectrum. The sensitizer is able to establish strong anchorage on the surface of the TiO₂ over a wide pH range. Under broad band visible irradiation, the sensitizer can inject electrons into the conduction band of the semiconductor. Using I^- as electron donor, the TiO₂-[Ru(terpy-Ph-PO₃H₂)₂]²⁺ system is able to mediate degradation of CCl₄ in aqueous medium.
