Abstract

New heteroleptic tris-cyclometalated iridium complex, $Ir(ppy)_2(dpq-5CH_3)$, was prepared, where ppy and $dpq-5CH_3$ represent phenylpyridine and 2(5'-methyl)- 4-diphenylquinoline, respectively. The heteroleptic iridium complex shows high luminescence efficiency by the intramolecular energy transfer from the energy absorbing ppy ligands to the luminescent $dpq-5CH_3$ ligand leading to a decrease on quenching or energy deactivation.
