Nanometer-sized supramolecular assemblies created by the simple inclusion complexation of host cyclodextrins (CDs) and guest molecules have attracted more and more attention in recent years because of their potential to serve as molecular devices and molecular machines, as well as functional materials.[1–4] Indeed, CDs can be threaded on a polymer chain to form a polyrotaxane and extended to molecular tubes through the cross-linking of adjacent CD units in a polyrotaxane.
