title: Chemical control of double barrier tunnelling in alpha,omega-dithiaalkane molecular wires.
abstract: Single molecule conductance measurements on 1,4-bis-(6-thia-hexyl)-benzene derivatives reveal (i) that benzene rings serve as an effective indentation in the tunnelling barrier, and (ii) that more electron-rich benzene rings give higher conductances, consistent with hole conduction (i.e.via the benzene HOMO).
