Two in one : Two pseudorotaxanes can be combined to form a twin‐axial hetero[7]rotaxane (see picture) by using the copper‐catalyzed alkyne–azide “click” reaction. The synthetic route, in which twin‐axial and single‐axial rotaxanes are formed, combines self‐assembly and the formation of covalent bonds to ensure the correct positioning of the two types of rings in the final product.
