Chloride locks the rings : Debenzylation of a chloride‐templated N ‐benzyl pyridinium catenane, allows for a 180° “pirouetting” of the rings in the resulting neutral pyridyl catenane (see scheme). The catenane may be returned to its original co‐conformation by chloride recognition as evidenced in solution and in the solid state.
