Charge Transport in Photoswitchable Dimethyldihydropyrene-Type Single-Molecule Junctions
Publisher DOI
Abstract
The conductance properties of a photoswitchable
dimethyldihydropyrene (DHP) derivative have
been investigated for the first time in single-molecule
junctions using the mechanically controllable break
junction technique. We demonstrate that the reversible
structure changes induced by isomerization of a single
bispyridine-substituted DHP molecule are correlated with
a large drop of the conductance value. We found a very
high ON/OFF ratio (>104) and an excellent reversibility
of conductance switching.
