| 摘 要： | 合成了以RE3 (Sm3 ,Eu3 ,Tb3 ,Dy3 )及Tb3 掺杂Ln3 (La3 ,Gd3 ,Y3 )为中心,以对叔丁基杯8]芳烃(LH8)及DMF,DMSO为配体的两个系列14种同核与掺杂稀土固体配合物,对其进行了元素分析、摩尔电导、热谱、红外光谱、紫外光谱、核磁共振氢谱的测定及荧光性能研究.荧光光谱的测试表明,所有Tb3 及其掺杂配合物具有较强的特征荧光,第二配体DMF对Tb3 及其掺杂配合物的荧光增强作用比DMSO更明显,掺杂荧光惰性离子对Tb3 的荧光增强作用顺序为La3 ＜Gd3 ＜Y3 . |

| Abstract: | Fourteen solid coordination compounds of rare earth(Sm~ 3 , Eu~ 3 , Tb~ 3 and Dy~ 3 and Ln~ 3 (La~ 3 , Gd~ 3 and Y~ 3 )-doped Tb~ 3 with p-tert-butyl-calix8] arene (LH_8) have been synthesized and characterized. Elemental analysis, rare erth complexometry, ~1H NMR spectra and TG-DTA have been studied. The results suggest that the complexes have the composition of RE_2(LH_2)(DMSO)_5]DMSO, RE_2(LH_2)(DMF)_5]2DMF, LnTb(LH_2)(DMSO)_5]DMSO and LnTb(LH_2) (DMF)_5]2DMF respectively. Fluorescence spectrum suggests that the Tb~ 3 complexes have characteristic luminescence, and its fluorescence intensity is enhanced after doping with La~ 3 , Gd~ 3 and Y~ 3 . The influence of the doping ions and two neutral ligands(DMSO and DMF) has also been discussed. In addition, the fluorescence lifetime of some complexes has been investigated. |
