| Abstract |
Six new cyclometalated iridium complexes of terphenyl-modified phenylimidazolinate ligands (tpim) were synthesized and characterized in order to examine the effect of bulky substituents on the structure-property relationship of these iridium complexes. Introducing bulky groups on the phenylimidazole ligand can effectively block the transition of nonradiative 3MC state and improve the emission lifetime. In order to demonstrate the bulkiness effect, X-ray single crystal structure analysis and theoretical quantum chemistry calculations were performed, and photophysical and electrochemical measurements were carried out. These results indicated that the terphenyl-phenylimidazolinato iridium complexes have potential application in fabrication deep-blue phosphorescent organic light-emitting diode devices. |
