Structure–Property Relationships Based on Swain–Lupton Constants in Homoleptic Phenylimidazolinato Iridium(III) Complexes |
| 초록 |
F-substituted complexes (TPIF and ITPIF) exhibited strong absorption band and emissive energy than that of the cyano-substituted complexes (TPICN and ITPICN). All of the terphenyl modified 2-phenylimidazole iridium complexes showed their quantum yields within the range of 33~50%. And the terphenyl group helped iridium metal center avoid proceeding non-radiative process. It was revealed that the EWG of the cyclometalated phenylimidazole ligands contributes substantially to both the HOMO and LUMO of the iridium complexes, the concurrent introduction of an ‒F and ‒CN groups on the phenyl ring relative to the Ir metal may lead to a favorable synergetic substituent effect on the color-tuning direction. This may represent a facile yet effective molecular design strategy for Ir(III) complexes with a desirous emission color. |
