Synthesis, Characterization, and Device Fabrication of Homoleptic Phenylimidazolinato Ir(III) Complexes Geometrically Confined with Bulky m-Terphenyl Group |
초록 |
Series of six terphenyl-modified phenylimidazolinato Ir(III) complexes with various substituents at 4-position of phenyl ring and 5-position of terphenyl ring were prepared. We have come up with the idea of implementing sterically bulky ligand that can help the metal-centered triplet state unstable; this brings us to use the terphenyl ligands. It was found that the bulkiness control of substituent on imidazole ring plays an important role in emission behavior of Ir-complexes. We performed theoretical quantum chemical calculations and measured experimental temperature dependent emission lifetime to explain the importance of bulky substitution in designing blue emissive Ir(III)-complex. Implications of the present observations and mechanism are discussed in detail. |
