摘要
本文首次合成了邻香兰素(3-甲氧基-2-羟基苯甲醛)与乙二胺、联苯胺、邻苯二胺、间苯二胺、对苯二胺缩合而成的双希夫碱(分别用L^1,L^2,L^3,L^4,L^5表示)的硝酸铕(Ⅲ)配合物,对它们进行了元素分析、摩尔电导、红外光谱、X射线光电子能谱测定,确定了组成,推断了结构,并研究了它们的热稳定性和发光特性。
The complexes of Europium(Ⅲ)nitrate with bis-schiff bases derived from o-vaniilin and ethylene-diamine, benzidine, o-phenylenediamine, m-phenylenediamine,p-phenylenediamine(indicated as L1, L2, L3, L4, L5, respectively) have been synthesized for the first time.The compositions and proposed structures are studied with the measurements of elemental analysis, molar conductance,infrared spectra,x-ray photoelectron spectra.Their thermal stabilities and luminescence properties are also studied.
