title: Slow excited state injection and charge recombination at star-shaped ruthenium polypyridyl compounds--TiO2 interfaces.
abstract: The excited states of two star-shaped nanometre-sized ruthenium polypyridyl compounds were largely unchanged when anchored to nanocrystalline TiO(2) thin films due to a highly symmetrical and rigid ligand structure that isolated the chromophoric core from the semiconductor. Interfacial electron transfer occurred on unusually slow time scales.
