Fast spinning motion is observed in a copper( I ) rotaxane. This “motor‐like” molecule consists of an axle, bearing two bulky stoppers at its ends, and a ring containing two differrent coordination sites, each of them corresponding to the preferred situation for copper( I ) or copper( II ). Thus, using electrochemistry, the axle can be forced to oscillate inside the wheel.
