水杨醛缩邻氨基苯甲酸Schiff碱稀土配合物的合成

摘要

Synthesis of salicylaldebyde-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 photolutninescence, Y( III ) 、La( III)、Eu( III)、Sm( III ) four rare earth complexes could produce fluorescence in S00-700nm range under the excitation source, the peak wavelength were 551 nm、 556nm,547nm and 550nm.%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、IB、UV、1H NMR及热失重分析,确定配合物组成为REL( H2O)C12·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.
