Charge transfer dynamics between an adsorbed molecule and a rutile TiO2(110) surface have been investigated in three organometallic dyes related to multicenter water splitting dye complexes: Ru 535 (cis-bis(isothiocyanato)bis(2,2′-bipyridyl-4,4′-dicarboxylato)-ruthenium(II)), Ru 455 (cis-bis(2,2′-bipyridyl)-(2,2′-bipyridyl-4,4′-dicarboxylic acid)-ruthenium(II)), and Ru 470 (tris(2,2′-bipyridyl-4,4′-dicarboxylic acid)-ruthenium(II)). The adsorption of the dye molecules on the rutile TiO2(110) surface has been studied using core-level and valence photoemission. Dye molecules were deposited in situ using ultrahigh vacuum electrospray deposition. Core-level photoemission spectra reveal that each complex bonds to the surface via deprotonation of two carboxylic groups. All three dye complexes show evidence of ultrafast charge transfer to the TiO2 substrate using the core-hole clock implementation of resonant photoemission spectroscopy.
