Synthesis and Spectroscopic Analysis of Complex Eu(o-ClC_6H_4OCH_2COO)_3·2,2′-bipy

以邻氯苯氧乙酸和 2 ,2′ 联吡啶 (2 ,2′ bipy)为配体 ,合成了Eu3 +的三元混配配合物。用元素分析确定其组成为Eu(o ClC6H4OCH2 COO) 3 ·2 ,2′ bipy ,并对该配合物进行了红外 ,紫外 。

This work has synthesized a title complex using rare earth ion Eu 3+ with the o-chlorophenoxyacetic acid and 2,2′-bipyridine.The chemical formula of the complex was determined to be Eu(o-ClC 6H 4OCH 2COO) 3·2,2′-bipy by elemental analysis, analysis of IR,UV ,fluorescence spectra.The ternary turopium complex display intense fluorescence,the intensity of 5D 0→ 7F 2 line in much higher than that of the 5D 0→ 7F 1 line,which shows low symmetry of the Fe 3+ ion site in the complex.
