摘要
合成了Cd(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、摩尔电导率等方法,对配合物进行了表征。圆二色性研究发现,配合物在208nm和228nm处呈正科顿效应,而在220nm和238nm处呈负科顿效应。荧光性质研究结果表明,配合物的特征荧光发射峰出现在460nm、478nm和584nm处,荧光寿命τ460、τ478和τ584分别为1.33ns、1.37ns和1.34ns。Cd(Ⅱ)配合物可发射白色荧光,是良好的荧光材料。
Cd(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 208nm and 228 nm,but showed negative Cotton effect at 220nm and 238 nm in CD study.The characteristic fluorescence peaks were located at 460nm,478nm and 584 nm in fluorescence spectrum of the complex,their lifetimesτ460,τ478 andτ584 were 1.33ns,1.37ns and 1.34 ns,respectively.The Cd(Ⅱ)complex exhibited white fluorescence and was a very good fluorescent material.
