摘要
以2-(2,4-二氟苯基)吡啶为主配体,2,2’-联吡啶为辅助配体,设计合成出了一种联吡啶铱配合物[Ir(dfppy)_(2)(bpy)]PF_(6)(dfppy=2-(2,4-二氟苯基)吡啶,bpy=2,2’-联吡啶)。通过元素分析、质谱、核磁共振谱、红外光谱和X射线单晶测试表征了配合物的化学结构,通过光致发光光谱和紫外可见光谱研究了配合物的光物理性能。结果表明,配合物的最大发射波长为515 nm,发光颜色为绿光。
A new cationic iridium(Ⅲ)complex,[Ir(dfppy)2(bpy)]PF_(6)(dfppy=2-(2,4-difluorophenyl)pyridine,bpy=2,2′-bipyridine),was successfully synthesized from chloride-bridged dimer(dfppy)_(4)Ir2(μ-Cl_(2))and 2,2′-bipyridine by using hexafluorophosphate as a counter anion.Its structure was characterized by elemental analysis,^(1)H NMR and^(13)C NMR,MS and FT-IR.Photophysical property of this complex was investigated.The results show that the maximum emission wavelength of the complex is 515 nm and the emission color is green.
