A bistable [2]rotaxane containing a halogen bonding benzimidazole-iodotriazole station directly conjugated to a naphthalimide station axle component is demonstrated to undergo macrocycle shuttling translocation only upon both protonation and chloride anion recognition. A naked-eye detectable colour response results from the co-conformational change of the host structure.
