Phosphorescent iridium(III) complexes based on 2-phenylimidazo[1,2-a]pyridine-type ligands: Synthesis, photophysical, electrochemical, and electrophosphorescent properties

New phenylimidazo[1,2-a]pyridine-based phosphorescent emitters of iridium have been developed. The balanced charge-transporting features for both kinds of charge carriers can bring about decent device performance, revealing the great potential of the phenylmidazo[1,2-a]pyridine-based IrIII phosphorescent materials.
