Comprehensive suppression of single-molecule conductance using destructive σ-interference
Marc H. Garner,Haixing Li,Yan Chen,Timothy A. Su,Timothy A. Su,Zhichun Shangguan,Zhichun Shangguan,Daniel W. Paley,Taifeng Liu,Fay Ng,Hexing Li,Shengxiong Xiao,Colin Nuckolls,Colin Nuckolls,Latha Venkataraman,Gemma C. Solomon +15 more
TL;DR: The molecular design presented here provides a proof-of-concept for a quantum-interference-based approach to single-molecule insulators, engineered so that conduction is fully suppressed by σ quantum interference even for molecules less than a nanometre long, could prove useful in molecular-scale electronic circuitry.

Non-chemisorbed gold-sulfur binding prevails in self-assembled monolayers
Michael S. Inkpen,Zhen-Fei Liu,Haixing Li,Luis M. Campos,Jeffrey B. Neaton,Latha Venkataraman +5 more
TL;DR: In this article, conductance measurements of different sulfur-bound single-molecule junctions show that thiols are not chemisorbed on gold, which strongly suggests that the thiol hydrogen is retained.

Stereoelectronic switching in single-molecule junctions
TL;DR: In this paper, the first single-molecule switch that operates through a stereoelectronic effect was demonstrated in permethyloligosilanes with methylthiomethyl electrode linkers.
Aromaticity Decreases Single-Molecule Junction Conductance.

TL;DR: It is found that the single-molecule conductance of these three wires correlates negatively with the resonance energy of the five-membered ring; the nonaromatic cyclopentadiene derivative has the highest conductance, while the most aromatic of this series, thiophene, has the lowest.

Timothy A. Su,Haixing Li,Rebekka S. Klausen,Nathaniel T. Kim,Madhav Neupane,James L. Leighton,Michael L. Steigerwald,Latha Venkataraman,Colin Nuckolls +8 more
TL;DR: The fundamental studies on the structure/function relationships of the molecular wires have guided the design of new functional systems based on the Si- and Ge-based wires and provided guidance for designing dielectric materials as well as molecular devices that require stability under high voltage bias.
