| 中文摘要: |
| 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)]PF6 (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。 |
| 英文摘要: |
| A new cationic iridium(Ⅲ) complex, [Ir(dfppy)2(bpy)]PF6 (dfppy=2-(2, 4-difluorophenyl) pyridine, bpy=2,2′-bipyridine), was successfully synthesized from chloride-bridged dimer (dfppy)4Ir2 (μ-Cl2) and 2,2′-bipyridine by using hexafluorophosphate as a counter anion. Its structure was characterized by elemental analysis, 1H NMR and 13C 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. |
