Utilizing the unique features of photochromic compounds to control aggregation enables the generation of photoresponsive gels. Self‐assembly mediated by hydrogen bonding in open and closed dithienylcyclopentene photoswitches carrying chiral amide moieties can be used to reversibly transcribe molecular into supramolecular chirality (see picture). Such molecular systems may lead to the design of future “smart” materials.
