Another thermal ratcheting step atropisomerizes the biaryl axis and repopulates the initial CT-1 state. When following the marked point on the PEG-linker chain during one full operational cycle a unidirectional circular rotation trajectory is established proceeding around a virtual axis with respect to the molecule. Although a molecular motor is used with intrinsic directionality for 360° rotation around its double bond axis, this motion is inhibited within the small macrocycle structure.
