Creating molecular components with controllable electronic properties is crucial to the realization of nanoscale devices. Now, a single-molecule conductance switch that operates through a stereoelectronic effect has been developed. The sub-ångström control of a scanning tunnelling microscope is used to switch reversibly between two distinct sets of rotational isomers, which differ greatly in their electronic character.
