A series of hetero [4]-, [5]- and [6]rotaxanes containing both cucurbit[6]uril (CB[6]) and γ-cyclodextrin (γ-CD) as the macrocyclic components have been synthesized via a threading-followed-by-stoppering approach. Due to the orthogonal binding of CB[6] to ammonium and γ-CD to biphenylene/tetra(ethylene glycol), the [n]rotaxanes display a specific sequence of the interlocked macrocycles. In addition
通过穿线合成了一系列含有葫芦[6]尿素(CB [6])和γ-环糊精(γ-CD)作为大环组分的杂[4]-,[5]-和[6]轮烷。循序渐进的方法。由于CB [6]与铵和γ-CD与联苯/四(乙二醇)正交结合,[ n ]轮烷显示了互锁的大环的特定序列。另外,尽管γ-CD相对于轴的正交平面不对称,但仅获得一种[6]轮烷的立体异构体。
