Abstract

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 ...
