Slide‐ring topological gels with mobile cross‐linking units are a new class of soft materials that exhibit distinct features differing from those of conventional chemically or physically cross‐linked gels. Photoresponsive behavior arising from the dynamic nature of the cross‐linkers is demonstrated for a slide‐ring gel prepared by adding azobenzene units to the mobile α‐cyclodextrin units of a poly(ethylene oxide)‐based polyrotaxane (see figure).
