| 英文摘要 | 利用环金属配体2-(4',6'-二氟苯基)吡啶(dfppy)和副配体2,2'-联嘧啶(bpm)合成了一个铱配合物[Ir(dfppy)z(bpm)]Cl,通过1H NMR,质谱,元素分析及红外光谱对其进行了表征,并且测定了其晶体结构.同时利用得到的中间配合物[Ir(dfppy):(bpm)]+[Ir(dfppy)2(Cl)2]n晶体结构讨论了配合物形成过程.对配合物[Ir(dfppy)2(bpm)]Cl的紫外可见吸收光谱和发光光谱的研究表明,其常温发射位于609 nm处,初步推测该磷光发射可能来自金属到配体的电荷转移(MLCT)跃迁和配体自身,π→π*跃迁(LC)的混合.; An Ir-III complex [Ir(dfppy)(2)(bpm)]Cl was synthesized with 2-(4',6'-difluorophenyl)pyridne (dfppy) as cylcometalated ligand and 2,2'-bipyrimidine (bpm) as ancillary ligand. It was characterized by H-1 NMR, mass spectr-ometry, element analysis and FTIR spectra, and its crystal structure was measured. At the same time, the forma-tion of this complex was discussed by the crystal structure of mediated complex [Ir(dfppy)2(bpm)](+)[Ir(dfppy)(2) (Cl)(2)](-). The UV-Vis absorption and photoluminescence spectra of [Ir(dfppy)(2)(bpm)]Cl were recorded. The emission at room temperature peaked at 609 nm, and it was supposed that the phosphorescence might originate from the mixture of the MLCT (metal-to-ligand charge transfer) transition and ligand-centered pi ->pi* transition.
