Stimuli‐responsive supramolecular hydrogels are intelligent materials with potential applications in the biomedical and engineering fields. A. Harada and co‐workers constructed a novel supramolecular hydrogel from a guest‐modified cyclodextrin (CD) without a polymer backbone. Supramolecular fibrils are formed through host–guest interactions, and hydrogen bonds between the CDs cross‐link the fibrils to give the hydrogel. The hydrogel exhibits excellent chemical‐responsive properties with competitive guests, hosts, and denaturants. For details, turn to their Full Paper on page 687 ff.
