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579nm,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.
