Large‐area moleculartunnelingjunctions comprising self‐assembled monolayers of redox‐active molecules are described that exhibit two‐terminal bias switching. The as‐prepared monolayers undergo partial charge transfer to the underlying metal substrate (Au, Pt, or Ag), which converts their cores from a quinoid to a hydroquinoid form. The resulting rearomatization converts the bond topology from a cross‐conjugated

[reaction: see text] The synthesis of a molecularwire bearing an anthraquinone core and thioacetyl end groups for gold electrode binding is described. A model anthraquinone system, substituted with tert-butylthio groups, can be reversibly switched electrochemically from cross conjugated (low conductance "off") to linear conjugated (high conductance "on") via two-electron reduction/oxidation reactions
