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.
通过使用两种卟啉衍生物展示了一种氟化物可写入的存储系统。结构修饰实现了挥发性和非挥发性模式。对于这两种卟啉,添加F⁻会猝灭荧光,只有一种衍生物在去除F⁻后恢复到其初始荧光状态(见图)。非挥发性行为基于阴离子诱导的从卟啉到氧化卟啉原的转变。
