Abstract

New functionalized phenylpyridine ligands and their derived heteroleptic cyclometalated Ir (III) complexes have been synthesized. The complexes possess a combination of important properties:(i) blue emission,(ii) good photoluminescence quantum yields, and (iii) good solubility in organic solvents, making them very attractive as phosphorescent dopant emitters for solution-processable light-emitting devices.
