| 摘 要： | 设计合成了一种新的离子型铱配合物Ir(dmpmq)2(dtbpy)]PF6，该配合物以2-(3,5-二甲基苯基)-4-甲基喹啉为主配体，4,4''-二叔丁基-2,2''-联吡啶为辅助配体，六氟磷酸根为阴离子。通过核磁共振谱(1H-NMR，13C-NMR)、质谱(MS)、单晶X射线衍射(XRD)确认了配合物的化学结构，采用光致发光光谱(PL)和紫外可见光谱(UV-Vis)对其光物理性能进行了研究。结果表明，该配合物为单斜晶系，空间群为C2/c；配合物在二氯甲烷溶液中的最大发射波长为579 nm，为典型的黄光发射离子型铱磷光配合物。

| Abstract: | A new ionic iridium phosphorescent complex Ir(dmpmq)2(dtbpy)]PF6 was designed and synthesized with 2-(3,5-dimethylphenyl)-4-methylquinoline as the main ligand, 4,4''-di-tert-butyl-2,2''- bipyridine as ancillary ligand, and PF6-as anion. The chemical structure of the complex was confirmed by 1H-NMR, 13C-NMR, MS, IR, and single X ray diffraction(XRD). Its photophysical properties were studied by photoluminescence and ultraviolet-visble absorption. XRD studies revealed that the complex belongs to monoclinic system with space group of C2/c. In CH2Cl2 solution, the iridium complex exhibit yellow emission with a maximum emission peak at 579 nm. |
