The rotation of individual rotors can be driven electrically using electrons from a scanning tunneling microscope tip, as discussed by E. C. H. Sykes et al. in their Communication on page 9678 ff. Above the threshold energy of the CH stretch excitation, electrons selectively drive rotation, but not translation of the thioether rotors. The ability to rotate individual molecules on command will permit the interrogation of many important effects like rotational energy transfer along 1D molecular chains and rotational orientation switching in ordered arrays.
