Polyrotaxanes consisting of α ‐cyclodextrin and poly(ethylene glycol) are versatile building blocks for the construction and controlled degradation of multilayers. Degradation is based on “unlocking” the α ‐cyclodextrins by disulfide cleavage of the polyrotaxane capping groups. This disrupts the multivalent intermolecular interactions between the layers, leading to degradation.
