| 中文摘要: |
| 以2-(3,5-二甲苯基)异喹啉(mpiq)作为环金属配体，2,2,6,6-四甲基庚二酮(tmd)为辅助配体合成了红光铱配合物Ir(mpiq)2(tmd)，产率91.4%。采用元素分析、核磁共振谱、质谱、红外光谱及单晶X射线衍射表征了分子结构，采用紫外-可见吸收光谱和光致发光光谱研究了它的光物理性能。结果表明，该配合物呈稍微扭曲的六配位八面体配合物，为单斜晶系，C2/c空间群。在室温下最大发射波长为632 nm，为深红光发射铱磷光配合物。 |
| 英文摘要: |
| The red iridium complex Ir(mpiq)2(tmd) was synthesized with 2-(3,5-dimethylphenyl) isoquinoline (mpiq) as the ring metal ligand and 2,2,6, 6-tetramethylheptanedione (tmd) as the auxiliary ligand, and the yield was 91.4%. The molecular structure of Ir(mpiq)2(tmd) was characterized by elemental analysis, NMR (1H and 13C), MS and FT-IR and single crystal XRD, and its photophysical properties were studied by UV-Vis absorption spectroscopy and photoluminescence spectroscopy. The results showed the complex is in the monoclinic system with a space group of C2/c. Its maximum emission wavelength at room temperature is 632 nm, and it emits phosphorescent in deep red light. |
