摘　　要：合成了邻菲罗啉－Ｎ－氧化物（Ｌ１）及丙烯酸（ＨＬ２）与部分希土的三元配合物［ＲＥ（Ｌ１）（Ｌ２）３］（ＲＥ＝Ｌａ－Ｎｄ．Ｓｍ－Ｔｂ）．通过元素分析、红外光谱、紫外光谱、摩尔电导、热分析对该系列配合物进行了表征．研究了Ｅｕ（Ⅲ）、Ｓｍ（Ⅲ）配合物的荧光性质，讨论了阴离子对Ｅｕ（Ⅲ）配合物荧光性质的影响．The ternary complexes of rare earths with 1,10-phenanthroline-N-oxide(L1)andpropcnoic acid (L2) having the composihons [RE(L1) (L2)3] [RE=La-Nd,Sm-Tb) weresynthesized in methanol medium.The new complexes were characterized by elemental analysis,IR spcctra,UV spectra,molar conductances and TG-DTA techniques.The fluorescencespectra of the Eu(Ⅲ) complex and Sm(Ⅲ) complex have been invcstigated, and the effect ofanion on fluorescence property of Eu(Ⅲ) complex has been discussed.
