水杨醛缩对氯苯胺合铜的合成与发光性能

Synthesis and Fluorescence of A Cu(Ⅱ) Complex of N-salicylidene-p-chloroaniline

设计合成了席夫碱配体水杨醛缩对氯苯胺(HL)及其铜配合物(CuL2),由元素分析、摩尔电导率、红外光谱推测出配合物组成为CuL2。对比研究了水杨醛缩对氯苯胺和水杨醛缩对氯苯胺合铜在甲醇、无水乙醇、丙酮溶液中的荧光性质,由荧光光谱分析可以看出,配体与配合物能够发射较强的荧光,配合物CuL2的发光机理为配体的π*→n发光。

Schiff base ligand N-salicylidene-p-chloroaniline（HL） and its Cu（Ⅱ） complex CuL2 were synthesized and characterized by element analysis,molar conductance value,and IR spectra.The luminescent properties of HL and CuL2 were studied by fluorescence spectroscopy.The results showed that the ligand and CuL2 complex had luminescent properties in CH3OH,C2H5OH and CH3OCH3.Their photoluminescent peaks could be ascribed to the band of π＊→n transition in the ligand.
