Figure One (IMAGE) Osaka University Caption (Left) Chemical structures of completely insulated molecular wires derived from oligothiophene with nanometer length scales. The upper figure shows the flat conformation, while the lower figure displays the twisted form. (Right) Results of single-molecule conductance measurements, in which the conductivity is plotted as a function of oligomer length. The crossover from the tunneling regime to the hopping regime occurs at a shorter chain length in the flat nanowires owing to their increased conductivity.
