A novel photochromic diarylethene with a salicylidene Schiff base substituent has been synthesized and characterized. The could be used as multi-addressable fluorescence switch when triggered by light, protons metal ions. As result, two logic circuits were constructed the unimolecular platform using intensity at different wavelengths outputs appropriate combinational stimuli of UV/Vis TEA/TFA, Al(III)/EDTA inputs. Moreover, derivative was found to highly selective towards Al(III) significant color changes for potential applications colorimetric fluorescent chemosensors.
