A molecular Boolean mimic with OR, NOR, YES and INH functions: dual-ion recognition driven fluorescence “turn on”†
Abstract
A Naphthyl-based Schiff base (R) has been explored as a dual-ion receptor for Cu+2 and F− with a fluorescence “turn on” response at a single wavelength. The changes are attributed to the modulation of ICT and PET processes. The recognition behaviour demonstrates R as a Boolean mimic for computation of OR, NOR, YES and INH functions with a convenient reset mechanism.
