Molecular AND logic gate based on electric dichroism of a photochromic dihydroindolizine
Artikel i vetenskaplig tidskrift, 2005

(Chemical Equation Presented) Very ANDy: A photochromic molecular switch has been found to act as an AND Boolean logic gate. The switch takes as input both UV light, which causes photo-isomerization of a dihydroindolizine to an open, dipolar form, and an electric field, which aligns this isomer in solution (see scheme). The output of the gate is read as the electric linear dichroism response of the open isomer. The gate can be reset with visible light. © 2005 Wiley-VCH Verlag GmbH & Co. KGaA.
