Abstract

original image

Return trip included! The first molecular realization of a reversible logic operation with a simple cocktail of two classical fluorophores is demonstrated (see figure). Protons and anions, which serve as inputs, trigger independent fluorescence answer signals. Thus, XOR and YES gates are straightforward implemented, resulting in reversible logic behavior.
