Abstract

(Figure Presented) On the move! Upon oxidation in situ, a positively charged ring travels a few nanometers along the dumbbell-shaped component of a monolayer of soaplike, bistable [2]rotaxanes on water (see picture). This motion was probed by surface-sensitive X-ray scattering and establishes that bistable rotaxanes retain their switching capabilities even in condensed monolayer phases.
