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。 A series of heteronuclear complexes of mononuclear, homoponuclear and their non-fluorescent rare earth ions La3 +, Gd3 +, Y3 + with Eu3 +, Tb3 +, Tb3 +, and 2, 3-pyridinedicarboxylic acid (H2 QUI) The complexes were respectively introduced into the ternary complex of 1,10-phenanthroline (phen) and 2,2 ’-bipy (2,2’-bipy). The complexes were tested by IR and fluorescence spectroscopy. The results show that the fluorescence of multi-core complexes of terbium ions is better than that of mononuclear complexes. The introduction of nitrogen-containing ligands can improve the fluorescence of binary complexes of europium ions and terbium ions.
