Abstract:Electronic absorption, emission, and excitation spectra together with lumincscence lifetimes, have been measured for the mixed-ligand 1,10-phenanthroline/2-(2-pyridyl)quinoline complexes of ruthenum(II). Charge-transfer absorption and emitting states appear to be located on the individual ligands and there is evidence that energy transfer from the phenanthroline absorption state to the pyridylquinoline emitting state occurs.
