Ratchet motor design, photon-driven

A Novel, Photon-Driven Ratchet Motor Design... 

We have seen that biomotors driven by proton gradients or by ATP hydrolysis have evolved to perform many functions. Artificial motors designed to be driven by chemical reactions, photon absorption, or electron transfer have been created by Homo sapiens. The authors of this chapter have designed a photon-driven ratchet motor consisting of a dibenzofulvene rotor and a chiral, triaiylmethane stator. (Quantum yields for substituted dibenzofulvene rotors have been measured and are adequate for practical operation of the target motor.
