A novel approach to efficient and selective construction of [4]rotaxane was proposed to demonstrate the superiority of H-bonded azo-macrocycles in forging higher order rotaxanes. The single crystal structure reveals the importance of the interplay of multiple non-covalent bonding interactions, particularly π-stacking interactions, in stabilizing the host-guest complex. This may open an avenue to the synthesis of oligomeric mechanically interlocked molecules containing fewer stations but more rings.
提出了一种高效且选择性构建[4]轮烷的新方法，以证明氢键连接的偶氮大环在构建高阶轮烷方面的优越性。单晶结构揭示了多种非共价键相互作用，特别是π-堆积相互作用，在稳定主客体复合物中的重要性。这可能为合成包含较少站点但较多环的低聚机械互锁分子开辟一条途径。
