Molecular motors bearing a hydrophobic perfluoroalkyl chain in the rotor were assembled on gold film. The functionalized molecular motors preserved their rotary motion both in solution and on the gold surface. The electronic properties and the thickness of the self-assembled monolayer and the wettability of motor-functionalized surfaces were changed upon photo-isomerization using UV-light, which were confirmed by UV/vis absorption and X-ray photoelectron spectroscopies and the contact angle measurement.
