Five-state molecular switching of a rotaxane in response to weak and strong acid and base stimuli
Access this Article
This communication describes the base- and acid-induced fivestate translational isomerization of a rotaxane containing two pairs of N-arylamine and N-alkylamine centers as binding sites for two dibenzocrown-8 components. Gradual molecular shuttling of this rotaxane is achieved in response to both the amount and strength of the added acid or base.
