查看参考文献15篇

文摘 为寻求发光性能良好的配合物,设计合成了一种新的双酰胺配体1,4-二[(2′-苄胺甲酰基苯氧基)癸氧基]苯(L),并在氯仿和乙酸乙酯溶液中合成了其与硝酸钐、硝酸铕和硝酸铽的发光稀土配合物.元素分析数据表明稀土硝酸盐与配体形成的是 1∶1 型的配合物;红外光谱显示配合物具有相似的配位结构.对配体及其配合物的荧光进行了详细的研究,结果表明:钐、铕和铽配合物分别呈现出Sm~(3+)、Eu~(3+)、Tb~(3+)的特征发射,铕离子处于不对称中心格位,硝酸铽配合物荧光相对强度最大.
其他语种文摘 The study of the rare earth complexes has been an active research area,which may be attributed to the specific spectroscopic and magnetic properties of rare earth ions and the abundance of rare earth elements in our country. Amide-type ligands which are flexible in structure and have ‘terminal-group effects’,will shield the encapsulated rare earth ion from interaction with the surroundings effectively,and thus achieve strong luminescent properties. Aiming at good fluorescent rare earth complexes,a new diamide ligand 1,4-bis[(2′-benzylaminoformyl)phenoxyl-decatyl-oxy] benzene (L) and its Sm(Ⅲ),Eu(Ⅲ) and Tb(Ⅲ) complexes were synthesized for the first time. The analytical data indicated that the three rare earth complexes conform to a 1∶1 metal-to-ligand stoichiometries Ln(NO_3)_3·L. The IR spectra show that the three complexes have similar IR spectra,of which the characteristic bands have similar shifts,suggesting that they have a similar coordination structure. The fluorescence properties of the ligand and its rare earth complexes were investigated in detail on Hitachi F-4500 spectrophotometer. The results indicated that the Sm,Eu and Tb complexes exhibit the characteristic emissions of Sm~(3+),Eu~(3+) and Tb~(3+),respectively. The fluorescence of the ligand and Sm,Eu complex is weak and the Eu~(3+) is not in a centro-symmetric coordination site. The Tb complex shows strong fluorescence,which could demonstrate the ligand L is a good organic chelator for Tb~(3+).
