摘要: 合成了末端基为喹啉基的两个开链冠醚2,2' (乙撑二氧)二(8 喹啉氧基甲基)苯(L1)和2,2' (乙撑二氧)二(8 喹哪啶氧基甲基)苯(L2)与U(Ⅵ),Th(Ⅳ)的配合物;并使用1HNMR,IR,差热热重分析,摩尔电导率和元素分析等方法对配合物进行了表征;确定U(Ⅵ)配合物的组成为UO2LNO3NO3·3H2O(L=L1,L2);Th(Ⅳ)配合物的组成为ThL(NO3)2(NO3)2·nH2O(L=L1,n=1;L=L2,n=3)。

Abstract: U(Ⅵ) and Th(Ⅳ) complexes with two open-chain crow n ethers, 2,2’-(ethyleneioxy)bis(8-quinolyloxymethyl)benzene(L 1) and 2,2’-(ethylenedioxy)bis8-(quinaldyloxymethyl)benzene(L 2), are prepared and characterized by using 1H NMR, IR spectra, thermal analysis, molar conductivity and elemental analysis. The chemical formula of the U(Ⅵ) complexes is UO 2LNO 3NO 3·3H 2O(L=L 1,L 2),and ThL(NO 3) 2(NO 3) 2· n H 2O(L=L 1, n =1;L=L 2, n =3) for the Th(Ⅳ) complexes.
