The Cover Feature shows contracted (top) and extended (bottom) molecular models of unsymmetric bistable [c2]daisy chain rotaxanes with two different units as stoppers: an electron donor triarylamine and an electron acceptor perylene bisimide. The distinct cyclic voltammograms of the extended (blue) and contracted (red) structures highlight how the electrochemical properties of the stoppers can be altered by the shuttling event, that is controlled here by pH stimulation. This use of the mechanical bond could be, in principle, implemented towards the design of sensing devices. More information can be found in the Full Paper by E. Moulin, N. Giuseppone et al.
