Abstract

Although energy migration in rare-earth chelates has been the subject of many investigations in recent years, ¹ the phenomenon of intramolecular energy transfer in transition-metal compounds has received little attention. Recently a study of the luminescence of ruthenium (II) complexes has been reported in which d-d luminescence from the Ru(II)ion was observed whenever excitation of the complexes was carried out in the π→π∗ absorption bands characteristic of the ligands.². Thus, energy transfer from the ligand π system to the 4d-electronic system of the central chelated ion was demonstrated. The present communication reports the first observation of intramolecular energy transfer in analogous Os(II) compounds, where the transfer is from the ligand π-electronic system to the 5d-electronic states of the Os(II)ion.
