中文摘要: |
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。 |

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. |
