Solid-state tunnel junction devices were fabricated from Langmuir Blodgett molecular monolayers of a bistable catenane, a bistable pseudorotaxane, and a single-station rotaxane. All devices exhibited a (noncapacitive) hysteretic current-voltage response that switched the device between high- and low-conductivity states, although control devices exhibited no such response. Correlations between the structure and solution-phase dynamics of the molecular and supramolecular systems, the crystallographic domain structure of the monolayer film, and the room-temperature device performance characteristics are reported.
