A selective fluoride sensor and a digital processor with “Write–Read–Erase–Read” behaviour

Abstract

An easy-to-synthesize Schiff base as a selective and colorimetric fluoride sensor via modulation of intramolecular charge transfer (ICT) has been demonstrated. A typical dual-ion binding property along with its distinct reversibility has been explored for YES, NOR and INH logic functions and a potential “Write–Read–Erase–Read” mimic.
