| 中文摘要: |
| 设计合成了一种新的中性铱磷光配合物Ir(dmppy)2(popy)，该配合物以2,4-二(3,5-二甲基苯基)吡啶为环金属配体，2-(2-羟基苯基)吡啶为辅助配体。通过核磁共振氢谱和碳谱(1H-NMR、13C-NMR)确证了配合物的化学结构，采用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,采用热分析研究了配合物的热稳定性。该配合物在二氯甲烷中的最大发射波长为575 nm，为黄光发射铱磷光配合物。 |
| 英文摘要: |
| A new neutral iridium phosphorescent complex, Ir(dmppy)2(popy), was designed and synthesized with 2,4-bis(3,5-dimethylphenyl)pyridine as the cyclometalated ligand, 2-(2-hydroxyphenyl) pyridine as the ancillary ligand. The chemical structure of the complex was confirmed by 1H-NMR, 13C-NMR and MS. Its photophysical properties were studied by ultraviolet-visble and photoluminescence absorption. Its thermal stability was mearsured by TG. In CH2Cl2 solution, the iridium complex exhibit yellow emission with a maximum emission peak at 575 nm. |
