【摘要】 以对甲基苯甲酸、大茴香酸、间氯苯甲酸、对羟基苯甲酸、苯甲酸为第一配体,丙烯酰胺为活性配体,合成了5种新的铕芳香羧酸丙烯酰胺三元配合物。通过元素分析,EDTA配位滴定分析,红外、紫外、荧光光谱分析和热分析对目标配合物的组成、结构进行了表征,并研究了它们的发光性能和热性能。结果表明,5种新的活性铕三元荧光配合物均具有良好的发光性能,各芳香羧酸向铕离子传递光能的能力为:苯甲酸>对甲基苯甲酸>大茴香酸>间氯苯甲酸>对羟基苯甲酸,若能将这些含活性配体丙烯酰胺的铕三元荧光配合物引入高分子化合物中可望合成出键合型铕高分子发光材料。更多还原

【Abstract】 Five ternary complexes have been synthesized from europium with aromatic carboxylic acid(p-methylbenzoic acid, methoxybenzoic acid, m-chlorobenzoic acid, benzoic acid, p-hydroxylbenzoic acid) and acrylamide; and also characterized by means of elemental analysis, thermal analysis, FT-IR spectra and UV spectra. Fluorescence spectra show five ternary complexes have nice luminescent properties, the sequence of ability that the aromatic carboxylic acids transfer light energy to europium ion is as follows: benzoic acid > p-methylbenzoic acid > methoxybenzoic acid > m-chlorobenzoic acid > p-hydroxylbenzoic acid. At the same time, the ternary europium complexes containing a reactive ligand acrylamide will possibly have potential application on the fabrication of bonding-type europium polymer luminescent materials.更多还原
