吡唑啉酮类钐配合物的合成及其光谱分析

The Synthesis And Characterization of Pyrazolone Samarium Complexes

通过1-取代苯基-3-甲基-4-α-噻吩甲酰基-5-吡唑啉酮配体与稀土离子钐进行络合反应制备了二元及三元吡唑啉酮类钐配合物,并通过核磁共振、红外光谱和元素分析对其进行表征,证明二元配合物的化学式为Sm(L)3(C2H5OH)2,三元配合物的化学式为Sm(L)3(Phen)2(L=1-取代苯基-3-甲基-4-(α-噻吩甲酰基)-5-吡唑啉酮)。经过研究其紫外吸收光谱和荧光光谱表明配合物的吸收光谱主要来源于第一配体,配合物具有荧光。

By complexation of 1 - （ Substituted benzene hydrazine） - 3 - methyl - 4 - （ α - thenoyl） - 5 - pyrazolo- ne ligand with samarium ion, binary and ternary pyrazolone samarium complexes were obtained. Their structures were established on the basis of IR, 1 H NMR, and elemental analysis. The result indicated that the composition of binary com- plex was Sm（L） 3 （ C2H5OH） 2 and the composition of ternary complex was Sm（L） 3 （Phen） 2- Ultraviolet absorption spec- tra and fluorescence spectra showed that energy absorption was mainly from the first ligand and had fluorescence.
