| 摘 要： | 合成了5种新型镧掺杂铕的2,5-噻吩二羧酸(H2L)、1,10-菲咯啉(Phen)四元异核配合物,通过元素分析、TG-DTA、红外光谱法确定其组成为(EuxLay)2L3(Phen)2·4H2O(x∶y=0.90∶0.10、0.70∶0.30、0.50∶0.50、0.30∶0.70、0.10∶0.90),配体的羧基与稀土离子以螯合双齿配位。荧光光谱测试表明镧对铕的配合物有荧光浓聚效应。

| Abstract: | Five new La-doped europium complexes with thiophene-2,5-dicarboxylic acid(H2L) and 1,10-phenanthroline(Phen) were synthesized and characterized by elemental analysis,TG-DTA and FT-IR spectra.The composition of the complexes is confirmed to be(EuxLay)2L3(Phen)2·4H2O(x∶y=0.90∶0.10,0.70∶0.30,0.50∶0.50,0.30∶0.70,0.10∶0.90),and the results show that carboxyl of the ligand chelates with rare earth ions in chelating bidentate form.Observed from fluorescence spectra,lanthanum ions have an accumulative effect on europium complexes. |
