摘要
用丙烯酸、氯化亚砜和对羟基苯甲酸为原料,合成了对丙烯酰氧基苯甲酸(PABA);以对丙烯酰氧基苯甲酸、二苯甲酰甲烷(DBM)为第一配体、邻菲罗啉(phen)为第二配体,合成了可聚合的Eu(PABA)(DBM)_2Phen四元配合物,通过红外光谱(IR)、紫外光谱(UV)、元素分析和~1H NMR对配体和配合物进行了表征。荧光光谱强度表明,对丙烯酰氧基苯甲酸(PABA)有利于Eu(PABA)(DBM)_2Phen四元配合物的光致发光。
P-propylene acly oxygen benzoic acid(PABA) was synthesized with propenoic acid, sulfoxide chloride and p-hydroxybenzoic acid. Polymeric Eu(PABA)(DBM)_2Phen was synthesized with p-propylene acly oxygen benzoic acid(PABA), DBM as first ligand and phen as second ligands. They were characterized by IR, UV, elemental analysis and ~1H NMR. Fluorescence spectrum intensity shows that para propylene acyl oxygen benzoic acid(PABA) is suitable for the photoluminescence of Eu(PABA)(DBM)_2Phen quaternary complex.
