摘要
本文采用溶剂萃取法和乙醇-水溶液析出法合成了六种轻希土与2-噻吩甲酰三氟丙酮(HTTA)和1,10-二氮杂菲(phen)三元配合物.通过元素分析、红外光谱、热重及荧光光谱等测试手段,考察了配合物有关性质,并确定了其组成为RE(TTA)3phen和RE(TTA)3phen·H2O(RE=La、Ce、Pr、Nd、Sm、Eu).
The solid state ternary coordination compounds of light rare earth clements with 2-thcnoyltrifluoroacetone (HTTA) and 0-phenanthroline(phen) have been synthesized by methods of ethanolic-water precipitation and solvent extraction. The composition of the coordination compounds determined by clemental analysis,TG and IR are RE(TTA),phen(RE=Pr, Nd, Sin) and RE(TTA)3 phen·H2O(RE=La, Ce, Eu). The fluorescence properties or the coordination compounds,especially Eu(TTA)3 phen·H2O has been studied in different organic solvent. The resultS show that the fluorescence intensity of Eu(TTA)3phen·H2O is stronger than others.
