Triptycylhelicenes 1 and 2 were examined as molecular rachets (see picture) in which the triptycene serves as the rachet wheel (a) and the helicenes as pawl (b) and spring (c). The ease of rotation of the triptycene wheel depends on the helicene springs and pawls, but do these have any influence on the direction of rotation?
