Artificial molecular motors hold great promise for application in responsive functional materials as well as to control the properties of biohybrid systems. Herein a strategy is reported to modulate the rotation of light‐driven molecular motors. That is, the rotary speed of a molecular motor, functionalized with a biphenol moiety, could be decreased in situ by non‐covalent substrate binding, as was established by 1 H NMR and UV/Vis spectroscopy. These findings constitute an important step in the development of multi‐responsive molecular machinery.
