Abstract: A series of homoleptic Ru(II) star complexes were synthesized and bound to semiconductor metal oxide nanoparticle films. In the nanosized, highly symmetrical “star”-shaped complexes, the Ru(II) center is coordinated to three identical bipyridine ligands carrying conjugated oligophenylenethynylene (OPE) rigid linker units terminating with carboxylic anchor groups. In this report, we describe how this concept is being applied toward the development of chromophoric units that are isolated from the surface of the semiconductor, and some possible advantages of this surface engineering strategy.
