Irradiation of acidic (pH 2) solutions of RuLb+ 2C1-(L = diisopropyl 2,2'-bipyridine-4,4'-dicarboxylate) in the presence of TiO, at 100°C leads to the loss of one bipyridyl ligand and the chemical fixation of RuL, at the surface of the TiO, particles through formation of Ru-0-Ti bonds. These surface
