Abstract

This work has synthesized a title complex using rare earth ion Eu3+ with the o-chlorophenoxyacetic acid and 2,2'-bipyridine. The chemical formula of the complex was determined to be Eu(o-ClC6H4OCH2COO)3.2,2'-bipy by elemental analysis, analysis of IR, UV, fluorescence spectra. The ternary turopium complex display intense fluorescence, the intensity of 5D0-->7F2 line in much higher than that of the 5D0-->7F1 line, which shows low symmetry of the Fe3+ ion site in the complex.

摘要

本工作采用稀土离子Eu3+与邻氯苯氧基乙酸和2,2'-联吡啶合成了一种标题配合物。通过元素分析、红外光谱、紫外光谱和荧光光谱分析确定该配合物的化学式为Eu(o-ClC6H4OCH2COO)3·2,2'-bipy。该三元铕配合物表现出强烈的荧光，5D0→7F2谱线的强度远高于5D0→7F1谱线，这表明配合物中Fe3+离子位点的对称性较低。
