摘要： 合成了14种稀土元素与甘氨酸(Gly)、L-丙氨酸(Ala)的混配型三元固态配合物RE(Gly)2.5(Ala)1.5(ClO4)3·H2O(RE=La～Lu,Pm除外).并对配合物进行了红外、核磁、荧光、X射线粉末衍射和热分析。铕(Ⅲ)、铽(Ⅲ)三元配合物的荧光强度(Eu:5D0→7F2;Tb:5D4→7F5,7F6)比相应铕(Ⅲ)或铽(Ⅲ)水合高氯酸盐增大10倍。

关键词: 稀土配合物, 甘氨酸, L-丙氨酸, 荧光光谱

Abstract: The ternary complexes RE(Gly)2.5(Ala)1.5(ClO4)3·H2O(RE=La～Lu except Pm;Gly=glycine;Ala=L-alanine) have been synthesized in aqueous solution and characterized by elemental analysis,amino acid analysis,IR,1H NMR,13C NMR, X-ray diffraction,thermal analysis and fluorescence spectrometry.The fluorescence intensities of the complexes of Eu(Ⅲ) and Tb(Ⅲ) (Eu:5D0→7F2;Tb:5D0→7F5,7F6) have increased by 10-fold as compared with those of the corresponding perchlorate hydrates of Eu(Ⅲ) and Tb(Ⅲ).

Key words: rare earth complex, glycine, L-alanine, fluorescence spectrumi
