The employed rotor is made of a flat fluorene moiety, often used as a stationary unit in the second-generation motors. It characterizes with a C 2v symmetry and, hence, its rotation by 180 • leaves the system unchanged from a chemical point of view. Eventually, for a fixed-chirality operation cycle, the proposed motor is bistable, in similarity to its second-generation parent. Furthermore, the rotating-fragment high symmetry assures it does not contribute to the total-system electric dipole moment.
