We report a molecular [2]rotaxane which comprises a molecular cage and a dumbbell-shaped component, in which translational isomerism can be performed reversibly through an in situ anion exchange process, that is, sequential addition of Bu4NCl/ AgPF6 reagent pairs. The [2]rotaxane incorporates two pyridinium and two dialkylammonium centers and functions as a triply operable molecular switch, which can be controlled through altering the polarity of the solvent, adding acidic and basic reagents (TFA/Et3N), and the varying the nature of the counteranions (Cl- vs PF6-).
