摘要:

L-苯丙氨酸和邻香兰素为原料,合成了L-苯丙氨酸缩邻香兰素希夫碱配体及其稀土金属(铽、铕)配合物。经元素分析、红外光谱、紫外光谱分析,确定配合物的组成分别为[Tb2(H2O)2(SL)4](NO3)2[Eu2(H2O)2(SL)4](NO3)2SL=C17H17O4N。用荧光光谱研究了配体和配合物的光物理性能。结果表明,配体和配合物都具有较强的荧光性能;配合物具有良好的热稳定性(分解温度达580 ℃)。

Abstract:

A Schiff base ligandL-phenylalanine-o-vanillinand its rare earthTbEucomplexes were synthesized. The complexes were characterized by elemental analysisIR spectrometryUV-vis as [Tb2(H2O)2(SL)4](NO3)2[Eu2(H2O)2(SL)4](NO3)2SL=C17H17O4N. The photophysical properties of the ligand and complexes were investigated by fluorescence spectroscopy. The result showed that the ligand and complexes exhibited good fluorescenceand complexes exhibited good thermal stabilitydecomposition temperatures reached 580 .
