水杨醛缩邻氨基苯甲酸Schiff碱稀土配合物的合成

Synthesis of salicylaldehyde-o-aminobenzoic acid Schiff base and itsrare earth complexes

报道了水杨醛缩邻氨基苯甲酸及其四种稀土配合物的合成,通过元素分析、IR、UV、1H NMR及热失重分析,确定配合物组成为REL(H2O)Cl2.H2O(RE=Y、La、Sm、Eu);测试了配合物的荧光性,在激发光源辐射下,Y(Ⅲ)、La(Ⅲ)、Eu(Ⅲ)、Sm(Ⅲ)四种稀土配合物在500-700nm区域产生荧光,λmax分别为551nm、556nm、547nm和550nm.

Synthesis of salicylaldehyde-o-aminobenzoic acid Schiff base and its four rare earth complexes were reported.It showed that complexes had the general formula of REL（H2O）Cl2·H2O（RE=Y、La、Sm、Eu）by elemental analysis、IR、UV、1H NMR and TG-DTG.The fluorescence properties of compexes were studied by photoluminescence,Y（Ⅲ）、La（Ⅲ）、Eu（Ⅲ）、Sm（Ⅲ）four rare earth complexes could produce fluorescence in 500-700nm range under the excitation source,the peak wavelength were 551nm、556nm、547nm and 550nm.
