使用1 H NMR光谱和电喷雾电离质谱法研究了葫芦[7]尿素与一系列N-取代的N-甲基哌啶鎓,N-甲基吡咯烷鎓和N-甲基吗啉鎓阳离子之间的主-客体络合物的形成。由十甲基链桥接的包含N-甲基杂环首基的阳离子与葫芦丝[7]尿嘧啶形成顺序的1:1([2]假轮烷)和2:1主体-客体复合物。葫芦素起初位于十甲基链上,但是随着主体分子的进一步添加,主体易位至阳离子N-发生杂环首基。通过竞争性1 H NMR结合实验确定的葫芦素主体-客体稳定性常数的大小顺序遵循季铵阳离子疏水性的趋势。

1 : 1 ([2]pseudorotaxanes) and 2 : 1 host–guestcomplexes with cucurbit[7]uril. The cucurbituril initially resides over the decamethylene chain, however with further additions of the host molecule a translocation of the hosts to the cationic N-heterocyclic head groups occurs. The order of the magnitude of the cucurbituril host–gueststability constants, determined by competitive 1H NMR binding experiments
