【摘要】 合成了一系列Eu3+和Tb3+与 2 ,3-吡啶二甲酸 (简称H2 QUI)的单核、同多核及它们分别与非荧光性稀土离子La3+,Gd3+,Y3+的异多核配合物 ,并对单核配合物分别引入含氮配体 1,10-邻菲咯啉 (简称 phen)和 2 ,2’ -联吡啶 (简称 2 ,2’ -bipy)生成三元配合物。对这些配合物进行了红外、荧光光谱的测试和表征。结果表明 :铽离子的多核配合物荧光性能优于单核 ,而含氮配体的引入均能提高铕离子和铽离子二元单核配合物的荧光性能。更多还原

【Abstract】 A series of Eu(Ⅲ),Tb(Ⅲ) mononucleur and homomultinucleur complexes with 2,3-pyridinedicarboxylic acid and their heteronucleur complexes with La(Ⅲ),Gd(Ⅲ) and Y(Ⅲ) have been synthesized.Data show that the fluorescent performance of heteronucleur or homomultinucleur complexes of Tb(Ⅲ) are much better than that of the corresponding mononucleur complexes.Eu(Ⅲ),Tb(Ⅲ) mononucleur complexes with 2,3-pyridinecarboxylic again react with 1,10-phenanthroline(phen) or 2,2’-dipyridine to form a class of new solid complexes of rare earths.Data show that the fuorescent performance of this new complexes are also much better than that of the corresponding mononucleur complexes.更多还原
