Structure-Property Relationships 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). Interestingly, the ordering of the ILCT and MLCT trantision state have been controlled by modulating the electron-withdrawing substituents (‒F or ‒CN), resulting in significantly red-shifted emission at 298K as well as solvent polarity-dependent properties in CN compounds with strong CT characters. 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. |
