The unidirectional motion of molecular rotors is considered imperative for directing movement at the molecular level. Thus, we sought to consider how non-directional motion manifests and effects diffusion in small pore systems, for both the azimuthal and altitudinal rotors. In fact, such a case reassembles the scenario of rotors frequently incorporated in the backbone of porous frameworks but not governed by a stimulus, such as light. To investigate this, we conducted similar simulations as described in the previous two sections, but with the absence of the bias torque. This resulted in non-directional motion of the rotors (Fig. ). Without the application of bias force, the rotation is observed to consecutively oscillate in random directions, clockwise or anti clockwise. The presence and dynamics of the confined LJ liquid is not observed to produce unidirectional or preferred directional rotation of the rotors.
