Abstract

Mechanical displacement of the ring by around 40% along the approximately 9-nm long dumbbell-shaped component has been seen in a bistable redox-controllable [2]rotaxane. Chemical oxidation of the tetrathiafulvalene recognition station (green, see scheme) in the dumbbell-shaped component, which also contains a 1,5-dioxynaphthalene recognition station (red), results in the cyclobis(paraquat-p-phenylene) tetracation (blue) undergoing translation from the much preferred green station to the second-choice, red station.
