稀土-对叔丁基杯[8]芳烃-N,N-二甲基甲酰胺配合物的合成、表征及铽的光致发光

Synthesis, Characterization of Rare Earth - N,N-Dimethylformamide Complexes with P-Tert-Butylcalixarene and Photoluminescence of Tb^(3+) Complex

在N,N-二甲基甲酰胺(DMF)溶液中,对叔丁基杯[8]芳烃(H8L=C88H112O8)与RE(NO3)3·4DMSO(RE=La,Sm,Gd,Tb,Dy)反应,合成了5种新的稀土固体配合物,通过元素分析、红外光谱和热谱等实验进行了表征,确定了配合物组成为RE(H6L)(NO3)(DMF)6(RE=La,Sm,Gd,Tb,Dy),在常温下研究了它们的固态粉末荧光光谱,结果发现,铽-对叔丁基杯[8]芳烃配合物具有良好的荧光性能。

The solid RE-H_8L coordination compounds were prepared by reaction of p-tert-butylcalixarene(H_8L) with RE(NO_3)_3·4DMSO(RE=La,Sm,Gd,Tb,Dy)in N,N-dimethylformamide (DMF).The RE coordination compounds have been characterized by the elemental analyses, IR spectra and TG-DTA.Its composition is proved to be RE(H_6L)(NO_3)(DMF)_6 (RE=La,Sm,Gd,Tb,Dy).The coordination number is 8. The fluorescence properties of the terbium complex have been investigated.
