摘要
分别合成了双水杨醛缩邻苯二胺双希夫碱过渡金属(Ni,Cu,Cd)配合物。通过元素分析,红外光谱、紫外光谱表征,结果表明,配合物中邻苯二胺的氮原子和水杨醛中酚羟基的氧原子均与金属离子配位成键。荧光光谱分析显示,在乙醇溶液中,配体主要以"醌式"结构存在,配合物主要以"醇式"结构存在,Cd配合物在不同的激发光激发下,存在"醌式"和"醇式"两种结构。
Bis-salicylaldehyde-o-Phenylenediamine and its Ni,Cu,Cd complexes were prepared and characterized by elemental analysis,IR spectrum,UV spectrum.In complexes,metal ions were coordinated with N,O atoms of ligands.Fluorescence spectrum analysis showed,in ethanol solution,ligand had been exited in 'keto' structure;complexes had been exited in 'ethol' structure.Cd complex had equilibrium between'keto' and 'ethol'.
