  text: We explore the use of a photoacid in a chemical reaction cycle, which allows
    for the controlled sol‐to‐gel transition of a saccharide aldehyde‐based self‐assembling
    system. The modulation of the pH with light enables to generate chemical fuels
    in situ, thus triggering monomer activation and gelation. Our efforts represent
    a promising step toward dissipative self‐assembled systems with a higher degree
    of spatiotemporal control.
