In this contribution, we have proposed a new molecular rotary motor architecture in which, for the first time, the motor operation direction can be switched in situ, without the need for chemical modification of the system structure. This is achieved by application of an external electric-field pulse, and is intended to control chirality of motors deposited on a surface. Our study relies on quantum-chemical calculations and nonadiabatic molecular dynamics simulations performed for a specific chemical system, PFCN, designed to provide illustration for the proposed new motor type.
