The results of an investigation of the photochemical and photophysical properties of a series of complexes of the type [RuL2L′]Cl2 are reported, where L and L′ are bipyridine, phenanthroline, and methyl and phenyl derivatives of those ligands. All measurements were conducted in CH2Cl2. Luminescence lifetime and quantum yield data indicate that the ligand which accepts the electron in the localized MLCT excited state plays a significant role in the excited-state decay. HPLC analysis of the organic photoproducts from mixed-ligand complexes shows that flexible bipyridyl ligands are preferentially photolabilized, consistent with a dissociative mechanism involving an open-ended bipyridine in the transition state.
