摘要: An ionic iridium(III) complex [Ir(F2dpyb)(bzdpp)2Cl][OTf] with 1,3-difluoro- 4,6-di(2-pyridinyl) benzene (F2dpybH) terdentate ligand and benzyldiphenylphosphine (bzdpp) ligand was synthesized and characterized. The structure of iridium complex was verified by single-crystal X-ray crystallography. It crystallizes in monoclinic, space group P21/n with a = 14.3654(7), b = 23.0026(10), c = 15.7964(7) Å,β = 97.6029(11), V = 5173.9(4) Å3, Z = 4, F(000) = 2552, Dc = 1.645 Mg/m3, Mr = 1281.49 and μ = 0.071 mm-1. The UV-vis absorption and phosphorescence of the complex were discussed. The complex was ‘aggregation induced emission (AIE)’ active. It exhibited no emission in CH2Cl2 solution but strong blue-green emission in solid state under ultraviolet light excitation. The complex emitted a strong phosphorescence centered at 493 nm when doped in PMMA. Its lifetime is 0.755 μs and quantum yield is approximately 0.134.
