Influence of variations in the chromophoric ligand on the properties of metal-to-ligand charge-transfer excited states

The effects of variations in the chromophoric ligand on the properties of the metal-to-ligand charge-transfer (MLCT) excited states in the series [Os(PP)3)2+, [(PP)2Os(py)2]2+, and [(PP)2Os(LL)]2+ (PP = 2,2′-bipyridine, 1,10-phenanthroline, or a substituted derivative; py = pyridine; LL = das, dppm, dppb, dppene) have been investigated. From a series of electrochemical and photophysical measurements it has been determined that (1) substituent variations in the chromophoric ligands have a relatively minor effect on the dπ(Os) levels as evidenced by variations in E1/2 values for the ground-state Os(III/II) couples, (2) linear correlations exist between metal-to-ligand charge-transfer (MLCT) absorption or emission band energies and the difference in metal-based oxidation and ligand-based reduction potentials, E1/2(OsIII/II) - E1/2(PP0/-), and (3) a linear relationship between ln knr and the emission energy, Ecm, exists, consistent with the energy gap law . It appears that for nonradiative decay both the pattern of acceptor vibrations and the vibrationally induced electronic coupling term remain relatively constant as the chromophoric ligand is varied.
