A molecular‐scale gap array is introduced into a single‐layer graphene sheet by a lithographic dash‐line cutting process. Electrically active molecules are then covalently wired into these point contacts in high yield, thus forming stable molecular devices that for example are able to reversibly switch their conductance by chemical treatment.
