Molecular electronics: Chargetransportthrough a singlebenzenering is studied using the mechanically controlled break‐junction technique. The low‐bias conductance for a meta‐coupled benzenering is more than an order of magnitude smaller than that of a para‐coupled benzenering. This difference can be explained by a destructive quantuminterferenceeffects in the meta‐coupled benzene (see picture).
