Logic Control of the Fluorescence of a New Dyad, Spiropyran‐Perylene Diimide‐Spiropyran, with Light, Ferric Ion, and Proton: Construction of a New Three‐Input “AND” Logic Gate

Abstract

The fluorescence of a novel dyad with spiropyran and perylene diimide units can be significantly enhanced only under the combined actions of UV light, protons, and ferric ions (see Figure). This behavior corresponds to a new “AND” gate with three inputs.
