Abstract

By introducing a hexylcarbazolyl substituent into a phenylpyridine-based ligand, a Förster energy transfer from the carbazole moieties to the Ir(III) cores was observed in the heteroleptic cyclometalated Ir(III) complexes, resulting in an enhancement of luminescent efficiency. The phosphorescent OLED gave CIE coordinates of (0.21, 0.55) with a maximum external quantum efficiency of 7.16%.
