imidazolium interpenetrated assemblies is investigated. Two different approaches to reducing the macrocycle size are undertaken and the stabilities of the resulting pseudorotaxanes incorporating substituted imidazolium threading components studied using 1H NMR spectroscopy. Novel imidazolium axle containing interlocked rotaxane host structures are synthesised using chloride anion templated amide condensation
研究了改变大环组分的大小对阴离子模板化的咪唑鎓互穿组装体形成的影响。采取了两种减小大环化合物尺寸的方法,并使用1 H NMR光谱研究了掺入咪唑鎓取代组分的拟轮烷的稳定性。使用氯阴离子模板酰胺缩合和“封端”方法合成了新型的含互锁轮烷主体结构的咪唑鎓轴,并研究了“封端”轮烷的阴离子识别性能。
