Shine a light : A supramolecular hydrogel is formed by the glucan curdlan equipped with α‐cyclodextrins (CD‐CUR) and azobenzene‐modified poly(acrylic acid)(pAC 12 Azo). The sol–gel transition and the morphology of the supramolecular hydrogel can be switched by photoirradiation at the appropriate wavelength, which controls the formation of an inclusion complex between the α‐cyclodextrins and the azobenzene moieties (see picture).
