Light‐driven reversible intermolecular proton transfer at single‐molecule junctions
Angewandte Chemie International Edition, 2019•Wiley Online Library
Photoresponsive molecular systems are essential for molecular optoelectronic devices, but
most molecular building blocks are non‐photoresponsive. Employed here is a photoinduced
proton transfer (PIPT) strategy to control charge transport through single‐molecule azulene
junctions with visible light under ambient conditions, which leads to a reversible and
controllable photoresponsive molecular device based on non‐photoresponsive molecules
and a photoacid. Also demonstrated is the application of PIPT in two single‐molecule AND …

Abstract
Photoresponsive molecular systems are essential for molecular optoelectronic devices, but most molecular building blocks are non‐photoresponsive. Employed here is a photoinduced proton transfer (PIPT) strategy to control charge transport through single‐molecule azulene junctions with visible light under ambient conditions, which leads to a reversible and controllable photoresponsive molecular device based on non‐photoresponsive molecules and a photoacid. Also demonstrated is the application of PIPT in two single‐molecule AND gate and OR gate devices with electrical signal as outputs.
