Abstract
Embodiments of the present disclosure pertain to a composition that includes a rotaxane. The rotaxane includes a plurality of macrocyclic rings and a polymer with a molecular weight below 10,000 Da that is covalently appended to one or more sterically hindered molecules. The cavities of the macrocyclic rings are threaded onto the polymer. The plurality of threaded macrocyclic rings include a plurality of different segments that each include a plurality of threaded macrocyclic rings. Each of the plurality of different segments is in the form of a crystalline network. Further embodiments of the present disclosure pertain to methods of forming the rotaxanes by covalently appending one or more sterically hindered molecules onto a polymer and threading a plurality of macrocyclic rings onto the polymer. Additional embodiments of the present disclosure pertain to methods of manufacturing a three-dimensional structure by applying a composition of the present disclosure onto a surface.
