| 摘 要： | 以3-噻吩乙酸为第一配体合成钐、铕的二元配合物,以3-噻吩乙酸为第一配体,phen为第二配体合成钐、铕的三元配合物,通过元素分析和EDTA滴定分析确定其通式为REY32H2O、REY3phen（RE=Eu,Sm;Th=3-噻吩乙酸根,phen=邻菲啰啉）后,测定4种配合物的红外光谱、紫外光谱和荧光光谱及TG-DTG曲线。结果表明,由于第二配体的加入,对稀土离子的发光起到了敏化作用,增强了稀土离子的发光强度,并且三元配合物热稳定性比二元配合物的热稳定性好。

| Abstract: | Four solid complexes of rare earth with 3-thiopheneacetic acid and 1,10-phenanthroline were synthesized,and the general formula of these complexes was proved to be REY32H2O and REY3phen(RE=Eu,Sm;Th=3-Thiopheneacetic acid,phen= Phenanthroline)by element analyse and titration analyse.These complexes were characterized by IR spectroscopy,UV-spectroscopy,Fluorescent spectrum and TG-DTG.The results showed that RETh3phen had better thermal stability than REY32H2O,and that adding the second ligand could enhance Eu3+ or Sm3+ ion fluorescence intensity. |
