A variety of doublearmedcrownethers were prepared in which amine, amide, ester, nitrile and pyridine moieties were attached as cation-ligating sidearms to diaza-12-crown-4 ring. FAB-MS and 7Li/13C/23Na NMR binding and liquid membrane transport studies revealed that most of them exhibited Li+ cation selectivity, though corresponding single armed lariat ethers showed Na+ cation selectivity. Among
制备了多种双冠醚,其中胺,酰胺,酯,腈和吡啶部分作为阳离子连接侧臂连接至diaza-12-crown-4环。FAB-MS和7的Li / 13 C / 23的Na NMR结合和液体膜运输的研究显示,大多表现出锂+阳离子选择性,尽管相应的单武装套索醚表明的Na +阳离子选择性。其中,胺武装的diaza-12-crown-4衍生物具有最高的Li +离子选择性离子载体性能。它的传输效率和选择性特别优于市售的Li +离子选择性离子载体。
