Light-powered electrical switch based on cargo-lifting azobenzene monolayers
ANGEWANDTE CHEMIE-INTERNATIONAL EDITION, 47(18), 3407–3409.
author keywords: azo compounds; isomerization; molecular devices; molecular electronics; monolayers
TL;DR:
It is shown that, upon irradiation, azobenzene SAMs incorporated in a junction between an Au(111) surface and a mercury drop are able to lift the “heavy” Hg drop, and reversibly photoswitch the current flowing through the junction, which provides an ideal system as a potential “cargo” lifter.
