摘　　要：设计、合成了一种新型的基于联吡啶衍生物的阳离子型铱配合物,并通过元素分析、红外光谱、核磁共振谱及质谱分析确定了配合物的结构,并详细研究了其光物理性能。结果发现,配合物[Ir(mppy)2(Br2bpy)]+PF6-在625nm处具有很强的红光发射光谱。并通过溶剂缓慢挥发法培养出配合物的单晶,X射线单晶衍射仪对其结构进行了表征,获得了晶体结构参数,结果表明配合物为三斜晶系,P-1空间群。A novel charged iridium complex [Ir（mppy） 2（Br 2bpy）] ＋PF 6 - was designed, synthesized and characterized by elemental analysis, NMR （ 1H and 13 C）, MS and FT-IR. Photophysical property of this complex was investigated. Single crystals of complex was prepared, via a solvent evaporation technique, and was subjected to X-ray diffraction analysis. The results show complex is in the triclinic system with a space group of P -1 . A strong red-emission at 625 nm was observed in photoluminescence absorption spectra of the compound.
