Mechanistic studies of isomeric [2]rotaxanes consisting of two different tetrathiafulvalene units reveal that the movement of cyclobis(paraquat-p-phenylene) can be controlled

Abstract

Studies of isomeric [2]rotaxanes revealed that two different di-oxidised tetrathiafulvalene units (green) constitute different barriers for cyclobis(paraquat-p-phenylene) (blue) which can be used to induce directional movement with 90% efficiency.
