Supramolecular rotor : The interlocking of two porphyrin‐based molecular rotors into a bevel‐gear‐shaped structure is demonstrated (see figure). The mechanical interactions between the teeth of the two porphyrin rotors enabled them to mesh and rotate with almost identical activation energies. Switching the rotational activities of one rotor by using chemical stimulation induced a change in the cooperative rotational motions of both rotors.
