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。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(^(1)H and^(13)C),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.
