The designed system and its working principle have been formulated on the grounds of quantumchemical and nonadiabatic molecular dynamics simulations. Our conceptual starting point is the second-generation motor structure which we redesign by transfering the point stereogenic centre to a rotating, switchable unit eventually achieving the motor's axial chirality dependence on the orientation of the newly-added switch (Figure ). The proposed switch is electric-field sensitive: it characterizes with a large electric dipole moment, allowing for its orientation to be controlled with an external electric field. At the same time, thanks to optimized steric repulsion between the switch and the principal framework of the motor, after the switch orientation is set with the electric-field pulse, it is thermally (and optically) stable. Eventually, the motor can undergo a unidirectional, optically-driven rotation in the absence of the field. It should be stressed that the discussed effect requires control of the motor orientation with respect to the external electric-field source, thus, it is suited for controlling chirality of motors deposited on a surface. To assure all-R or all-S chirality of a manifold of motors, their stator components need to be aligned, e.g. in a way proposed in Figure (c), which can be achieved by proper functionalization of the surface by chemical or photolithographical means.
