合成了稀土氯化钕与N-乙酰-DL-丙氨酸(C5H9NO3,Ac-Ala)及咪唑(C3H4N2,Im)的三元配合物,通过元素分析和化学分析确定其化学组成为Nd(C5H8NO3)2(C3H5N2)2Cl3.4H2O,并通过FTIR、UV、1HNMR、13C NMR和X-射线粉末衍射的等手段对目标配合物的结构进行了表征.根据DSC和TG-DTG曲线研究了配合物的热分解过程.配合物水溶液的荧光性质测试表示,形成配合物后,配合物水溶液发生了荧光淬灭现象,在10-2~10-4mol/L浓度范围内荧光强度与溶液浓度呈正相关.
The ternary complex of rare earth neodymium chloride with N-acetyl-DL-alanine (C5H9NO3, Ac-Ala) and imidazole (C3H4N2, Im) was synthesized and its chemical composition was determined by elemental analysis and chemical analysis as Nd (C5H8NO3 ) 2 (C3H5N2) 2Cl3.4H2O, and the structures of the target complexes were characterized by means of FTIR, UV, 1HNMR, 13C NMR and X-ray powder diffraction.The structures of the target compounds were studied by DSC and TG-DTG curves Thermal decomposition of the complexes showed that fluorescence quenching occurred in the complex aqueous solution after the complex was formed. Fluorescence intensity was positively correlated with the concentration of the solution in the concentration range of 10-2 ~ 10-4mol / L.
