摘　　要：采用一种新方法制备无水稀土配合物,其中一步法直接合成三氯化铕的绝对无水乙醇溶液。在稀土配合物中引入带胺基的功能配体,使其与三氯化铕反应合成了两种两端含有胺基具有缩聚活性的配合物。以元素分析、红外光谱和紫外光谱对配合物的组成和结构进行表征,并以摩尔电导和荧光光谱对配合物的性质进行研究,结果表明,在DM F中配合物可作为聚合单体应用;粉末状态下,配合物具有高的荧光强度,荧光单色性好。A novel preparation method of anhydrous rare earth complexes is described, in which the absolute anhydrous solution of EuCl3 was prepared in one-step reaction. A functional ligand with amino group was introduced into rare earth complexes. Two kinds of rare earth complexes, which have two amino group in the two ends and represent the activity of polycondenstation, was synthesized by the reaction of EuCl3 and functional ligand in the medium of absolute anhydrous alcohol. The composition and structure of complexes was characterized by FT-IR, UV spectroscopy and elemental analysis, at the same time ,the properties of complexes was examined by molar conductivity and fluorescence spectroscopy. The results show that complexes could be used as copolymer monomers in the solvent of DMF and that complexes exhibit higher fluorescence intensity and nice monochromatic property in powder state.
