Cover Picture: Light‐Driven Transport of a Molecular Walker in Either Direction along a Molecular Track (Angew. Chem. Int. Ed. 1/2011)

UV light provides the energy required for directional transport of a small-molecule walker along a molecular track. In their Communication on page 285 ff., D. Leigh and co-workers describe how different sequences of stimuli can induce an 18-atom two-legged molecular unit to “walk” predominantly towards one or the other end of a track with four footholds.
