Abstract
New cis-Ru(3,3'-dcbpy)2(NCS)2 photosensitizer (where 3,3'-dcbpy is 3,3'-dicarboxy-2,2'-bipyridine) was synthesized using Ru(DMSO)4Cl2 as a starting material and characterized. Its photophysical and redox properties were compared with those of cis-Ru(4,4'-dcbpy)2(NCS)2 and cis-Ru(5,5'-dcbpy)2(NCS)2. The photoelectrochemical properties of the three dyes adsorbed on the surface of the nanocrystalline TiO2 electrodes as well as on self-assembly monolayers (SAMs) were investigated. The photocurrents generated by sensitized TiO2 electrodes were much higher than those by SAMs. And cis-Ru(4,4'-dcbpy)2 showed a most efficient photosensitizer in both systems. The mechanism is discussed in the paper. (C) 2000 Published by Elsevier Science S.A.
