摘要: 

以苯甲酸、对甲基苯甲酸、间氯苯甲酸、对氯苯甲酸、对羟基苯甲酸、对甲氧基苯甲酸为第一配体, 丁二酸为第二配体合成了六种新的铕三元荧光配合物. 通过元素分析、EDTA配位滴定分析、紫外光谱分析和红外光谱分析确定了标题配合物的组成及结构; 采用热分析仪研究了标题配合物的热稳定性能; 通过荧光光谱分析研究了标题配合物及对应二元配合物的发光性能. 结果表明: 标题配合物与对应的二元配合物相比发光强度大大提高.

关键词 有机高分子材料配合物合成丁二酸荧光    
Abstract

Six new ternary complexes of europium were synthesized with the first ligands of benzoic acid, p-methylbenzoic acid, m-chlorobenzoic acid, p-chlorobenzoic acid, p-hydroxylbenzoic acid, methoxybenzoic acid and the second ligand of butanedioic acid. Their molecular composition and structures were characterized by means of elemental analysis, EDTA titrimetric method, FT--IR and UV spectroscopies. The thermal stability properties of the title complexes were studied by thermal analysis instrument. The luminescent properties of the title complexes and their corresponding binary complexes were investigated by means of fluorescence instrument. The fluorescence spectra data show that the new ternary complexes have much higher luminescence intensity than their corresponding binary complexes.
