The additional inclusion of stilbene monomers within cyclodextrin rings strung on a stilene polymer leads to a supramolecular stabilization of the molecular necklace. This assembly can be transformed into a polyrotaxane (see drawing below) by photochemical formation of tetraphenylcyclobutane blocking groups.
