Abstract

Abstract : Control of directionality is of paramount importance if rectified motion in electroactive molecular machines should be realized. As illustrated in the cover artwork, the tetracationic ring (blue) in a tetraoxidized [2]rotaxane can follow two different tracks; it transpires that it is easier for the ring to follow a track in which it has to move across a monopyrrolotetrathiafulvalene dication (dark green) compared to the track in which it moves across a tetrathiafulvalene dication (light green). More information can be found in the Full Paper by J. O. Jeppesen et al. on page 6165 .
