Light-Driven Reversible Intermolecular Proton Transfer at Single-Molecule Junctions.

Angew Chem Int Ed Engl; 58(12): 3829-3833, 2019 Mar 18.
Artigo em Inglês | MEDLINE | ID: mdl-30689285
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.
