TLDR
Using a scanning tunneling microscope, high-bias conductance of single polyporphyrin molecular wires with lengths from 1.3 to 13 nm is measured and first-principles simulations revealed that the measured conductance is coherent resonant transport via a delocalized molecular orbital.Abstract:
Using a scanning tunneling microscope, we measured high-bias conductance of single polyporphyrin molecular wires with lengths from 1.3 to 13 nm. We observed several remarkable transport characteristics, including multiple sharp conductance peaks, conductances as high as 20 nS in wires with lengths of >10 nm, and nearly length-independent conductance (attenuation <0.001 A–1). We carried out first-principles simulations on myriad metal–molecule–metal junctions. The simulations revealed that the measured conductance is coherent resonant transport via a delocalized molecular orbital.read more

TL;DR: In this paper, benzene-1,4-dithiol molecules were self-assembled onto the two facing gold electrodes of a mechanically controllable break junction to form a statically stable gold-sulfur-aryl-solfur-gold system, allowing for direct observation of charge transport through the molecules.

Electron transport in molecular wire junctions.
TL;DR: Molecular conductance junctions are structures in which single molecules or small groups of molecules conduct electrical current between two electrodes and there is still limited correspondence between experimental and theoretical studies of these systems.
