合成了13种由稀土离子(La~(3+)、Pr~(3+)、Nd~(3+)、Sm~(3+)-Yb~(3+)和Y~(3+))与马来酸(C_4H_4O_4)和邻菲咯啉(Phen)形成的三元配合物。元素分析和微量水分测定确定其组成为Ln_2(C_4H_2O_4)_3(Phen)_2·4H_2O.研究了它们的紫外,红外吸收光谱,探讨了配合物的荧光性质及热稳定性。
Thirteen compounds of rare earth ions (La 3+, Pr 3+, Nd 3+, Sm 3+, Yb 3+ and Y 3+) were synthesized. Ternary complexes formed with maleic acid (C_4H_4O_4) and phenanthroline (Phen). Elemental analysis and determination of trace MoO3 were carried out to determine their compositions as Ln2 (C_4H_2O_4) _3 (Phen) _2 · 4H_2O. Their UV and IR spectra were studied. The fluorescence and thermal stability of the complex were also investigated.
