title: Intramolecular hydrogen bonding assisted charge transport through single rectifying molecule.
abstract: A novel diode molecule consisting of α-hydroxyphenyl pyridine motif was synthesized. Molecular self-assembly onto gold electrode surface leads to moderate rectifying behavior. The replacement of the hydroxyl proton by a methyl group leads to the disruption of intramolecular hydrogen bonding and yields a twisted molecular conformation. Comparing the current-voltage characteristics between these two compounds reveals that the presence of intramolecular hydrogen bonding substantially improves the molecular conductivity.
