Break it down : Gels formed from rotaxane cross‐linkers with end groups that are size‐complementary to the macrocyclic cavity of wheel components (see picture) were prepared. The network structure was maintained in polar organic solvents or in the presence of a base to prevent hydrogen bonding. Anion exchange enabled the selective and efficient de‐cross‐linking of the gels.
