1,1,1-三[(2′-甲酰苄胺苯氧)甲基]对甲苯磺酰氨基甲烷的合成及其稀土配合物的荧光性质

The synthesis of 1,1,1-tris{[(2′-benzylaminoformyl)phenoxyl]methyl}-p-toluene sulfonyl aminomethane and the luminescent properties of its rare earth complexes

合成了一个新的三足芳香酰胺型有机配体1,1,1-三[(2′-甲酰苄胺苯氧)甲基]对甲苯磺酰氨基甲烷,及其Eu(NO3)3和Tb(NO3)3的配合物,并通过元素分析、红外光谱、核磁共振氢谱和摩尔电导率进行了表征。室温下还研究了配合物的固体荧光性质,结果表明,两个配合物均能表现其稀土离子的特征荧光,但铽配合物的荧光要明显强于铕配合物,说明配体与铽之间的能级匹配要比铕好。

A new tripodal aryl amide type ligand, 1, 1, 1-tris t [ （ 2＇-benzylamlnoformyl ） phenoxyl ] methyl } -p-toluene sulfonyl aminomethane,and its Eu （ NO3 ）3, Tb （ NO3 ）3 complexes have been synthesized. The ligand and its complexes of Eu3 ＋ and Tb3 ＋ were characterized by elementary analysis, IR spectroscopy, 1HNMR and molar conductivity. The luminescent properties have also been studied in solid state at room temperature. Although the results indicate that the two complexes show the characteristic cmissions of rare earth, their luminescent spectrograms, show the luminescence of Tb^3 ＋ complex is much stronger than that of Eu3 ＋ complex, and it suggests that the energy transfer from this ligand to Tb^3 ＋ （antenna effect） is more effective than to Eu^3 ＋ .
