摘要
为了提高β-吲哚乙酸(IA)-铽二元固态配合物的荧光性能,在乙醇水溶液体系中,以邻菲啰啉(phen)作为第二配体,合成了铽与IA、phen三元固态配合物。通过元素分析、红外光谱及荧光光谱分析,确定了配合物的组成及其成键特征,研究了其荧光性能。三元配合物组成为Tb(IA)3.phen。三元配合物的荧光强度是二元配合物的近10倍。
To increase intensity of the complex of Tb with IA, in ethanol aqueous solution, the temary complex of Tb with IA and phen was prepared with phen as the second ligand. The composition, characteristics and fluorescent property of the complex was determined by element analysis, infrared spectrometer and fluorescent spectrometer. The ternary was composed of Tb（IA）3·phen. The fluorescence intensity of the ternary complex was about 10 times of that of binary complex. Moreover, the fluorescence enhancement effect of the second ligand phen on the complex was discussed.
