No backbone required : A supramolecular hydrogel has been synthesized from a guest‐modified cyclodextrin (CD) without a polymer backbone. The β‐CD forms supramolecular fibrils through host–guest interactions, and then hydrogen bonds between the CDs cross‐link the fibrils to give a hydrogel. Gel‐to‐sol transitions can be effected by adding a competitive guest or a denaturing reagent (see example).
