Nanoscale molecular-electronic devices comprising a single molecular monolayer of bistable [2]rotaxanes sandwiched between two 40-nm metal electrodes were fabricated using imprint lithography. Bistable current-voltage characteristics with high on-off ratios and reversible switching properties were observed. Such devices may function as basic elements for future ultradense electronic circuitry.
