摘要
合成了以桂皮酸、8-羟基喹啉为配体,以镱、铕为中心离子的稀土配合物,采用元素分析、摩尔电导、红外光谱、紫外光谱和荧光光谱法进行表征,并采用紫外光谱和荧光光谱研究了配合物与牛血清白蛋白(BSA)的相互作用。结果表明,随着配合物浓度的增加,BSA紫外光谱表现出明显的增色效应,配合物可有规律地猝灭BSA的荧光。
Two kinds of ternary complexes of rare earth, with cinnamic acid and 8-hydroxyquinoline were synthesized, and investigated by using elemental analysis, molar conductance, FT-IR, UV and fluorescence spectroscopy methods. The interactions of ternary complexes with BSA were studied by UV and fluorescence spectroscopy. Results showed that the absorption intensity of BSA increased with the increasing of complex concentration, and the fluorescence intensity of BSA was quenched regularly by the ternary complexes.
