Third generation molecular motors are equipped with two rotor units, which can rotate unidirectionally when powered by light. Although the solution behavior of these molecules has recently been studied, integrating them into useful nanodevices represents a major challenge. One key requirement is that these molecular motors are functional under ambient conditions. Moreover, it is crucial to have the achiral unidirectional rotary motion of these molecular motors happening on surfaces in order to get out of the Brownian regime. In the present study, the behavior of third generation molecular motors on modified HOPG surfaces was studied with STM under ambient conditions.
