Light-Driven Transport of a Molecular Walker in Either Direction along a Molecular Track

Walk this way! A walker unit is able to walk in either direction along a four‐foothold molecular track, 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...

Summary:Walk this way! A walker unit is able to walk in either direction along a four‐foothold molecular track, 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 molecular track is key for the achievement of directional transport through a Brownian ratchet mechanism.
