directional bias in the distribution of the walker on the track. The different length walker molecules exhibit very different walking behaviors: Systems n = 2 and 3 cannot actually "walk" along the track because their stride lengths are too short to bridge the internal footholds. The walkers with longer spacers (n = 4, 5, and 8) do step up and down the track repeatedly, but a directional bias under the acid-redox

Walk this way! A walker unit is able to walk in eitherdirectionalong a four‐foothold moleculartrack, depending on the sequence of application of four external stimuli: acid, base, UV light, and visible light in the presence of iodine (see picture). The isomerization of the stilbene moiety in the moleculartrack is key for the achievement of directional transport through a Brownian ratchet mechanism
