摘　　要：合成了Zn(Ⅱ)与1,2-亚苯基-双苯并咪唑(PBBM)的配合物,采用元素分析、UV、IR、摩尔电导率等进行表征。圆二色性研究发现,配合物在208 nm和230 nm处呈正科顿效应。荧光性质研究表明,配合物的特征荧光发射峰出现在450 nm和604 nm处,荧光寿命τ450和τ604分别为0.44 ns和0.31 ns。Zn(Ⅱ)配合物可发射白色荧光,是良好的荧光材料。Zn(Ⅱ)Complex with 1,2-phenylene-bisbenzimidazole(PBBM)was prepared and characterized by elemental analysis,UV,IR spectra and molar conductivity. It was found that the complex showed positive Cotton effect at 208 nm and 230 nm in CD study. The characteristic fluorescence peaks were located at 450 nm and 604 nm in fluorescence spectrum of the complex,their lifetimes τ 450 and τ 604 were 0.44 ns and 0.31 ns respectively. The Zn(Ⅱ) complex exhibited white fluorescence,it was a very good fluorescent material.
