摘　　要：本文合成了铕与ＴＴＡ及啉啡罗啉或表面活性剂Ｎ－氯代十六烷基吡啶两个三元络合物及铕－ＴＴＡ两元络合物。用元素分析、差热热重分析、红外与紫外光谱等方法表征了各化合物。测定了各络合物的固态及溶液荧光光谱，实验表明高对称八配位的Ｅｕ（ＴＴＡ）４ＣＰ络合物荧光强度最高。The solid complexes of europium with thenoyl trifluoroacetone phenanthroline (or cetylpyridinium chloride):Eu(TTA) 3phen,Eu(TTA) 4CP and Eu(TTA) 3H 2O are prepared and characterized by elemental analysis,molar conductivities,thermal analysis,UV spectra and IR spectra.The fluorescence of complexes has been determined.Because of the high symmetry and tough structure,the fluorescence intensity of the octadentate coordinated complex Eu(TTA) 4CP is the highest amongst the all.
