Abstract: Electronic absorption and luminescence spectra are reported for a series of complexes of type [Ru(tpy)(L-L)(py)]2+, where tpy and py are 2,2',2''-terpyridine and pyridine, and L-L represents the bidentate ligands bipyridyl, 4,4'-dimethylbipyridyl, 4-nitrobipyridyl, oxalate and acetylacetonate. The effect of solvent polarity and temperature on their spectral and light emission properties is studied. Energies are reported for the lowest-energy 3MLCT* excited state, and on the basis of these it is suggested that the complexes may make good triplet energy acceptors for use in organic and polymeric light emitting devices.
