Uncharged Amide-containing Rotaxanes

Although emphasis has been given so far to the self-assembly of positively charged rotaxanes, it needs to be noted that a number of uncharged rotaxanes, in which both the linear and cyclic components are neutral entities, have also been synthesised by a number of workers. Typically, these systems incorporate amide linkages and.
