| 中文摘要: |
| 以2-(3,5-二甲基苯基)喹啉(dmpq)为主配体，4,4'-二叔丁基-2,2'-联吡啶(dtbby)为辅助配体，合成出一种新型离子型铱配合物[Ir(dmpq)2(dtbbpy)]PF6。通过元素分析、质谱、核磁共振谱(1H和13C)、红外光谱和单晶X射线衍射表征了配合物的组成和化学结构，通过光致发光光谱和紫外可见光谱研究了配合物的光物理性能，通过热重分析测试了配合物的热稳定性。结果表明，所合成的苯基喹啉类铱配合物呈稍微扭曲的八面体配合物，其发射波长为587 nm，热分解温度为380℃，具有足够的热稳定性，是一种潜在的黄光材料。 |
| 英文摘要: |
| A new cationic iridium(Ⅲ) complex， [Ir(dmpq)2(dtbbpy)]PF6 (dmpq=2-(3,5-dimethylphenyl) quinolineyl, dtbbpy=4,4′-ditert-butyl-2,2′-bipyridine)，was successfully synthesized with dmpq as the cyclometalated ligand and dtbbpy as the auxiliary ligand. Its structure was characterized by elemental analysis, NMR(1H and 13C), MS and FT-IR, along with single crystal X-ray diffraction. Photophysical property and thermal stability of this complex were investigated. The results showed that the complex has good thermal stability and displays a strong yellow emission band at 587 nm. |
