Schematic representation of the threading/dethreading of a pseudorotaxane (a) and of the relative unidirectional transit of a macrocycle along a nonsymmetric molecular axle (b). By incorporating the system shown in (b) in a rotaxane

• molecular-level mechanical manipulators. As an example, macroscopic transport at the solid–liquid interface was driven by modifying the solid–liquid surface tension at a droplet front by using a molecular switch based on a SAM of rotaxane [8]. Central to the function of such systems are changes in the inter
