P‐159: Efficient Red Electroluminescent Devices Based on Inter‐Ligand Energy Transfer of Heteroleptic Tris‐Cyclometalated Iridium Complexes

AbstractRed heteroleptic tris‐cyclometalated iridium complex, Ir(ppy)2(dpq‐3‐F), have been characterized. When Ir(ppy)2(dpq‐3‐F) is placed in the excited state, the excitation energy is quickly intramolecular transferred from two ppy to one luminescent dpq‐3‐F. Thus, Ir(ppy)2(dpq‐3‐F) shows emission at 620nm from dpq‐3‐F. The device with Ir(ppy)2(dpq‐3‐F) showed superior electrical characteristics by decreasing self‐quenching.
