Abstract Written in the gel : A fluoride‐writable memory system has been demonstrated by using two porphyrin derivatives. Structural modification enabled both volatile and nonvolatile modes. For both porphyrins, fluorescence is quenched by addition of F − with only one of the derivatives returning to its initial fluorescent state following removal of F − (see scheme). Nonvolatile behaviour is based on anion‐induced conversion from porphyrin to oxoporphyrinogen.
