title: Push-pull [2]pseudorotaxanes. Electronic control of threading by switching ON/OFF an intramolecular charge transfer.
abstract: [reaction: see text] Addition of acid and base allows switching between two different structures in a push-pull bis(pyridinium)ethane axle, controlling its ability to form [2]pseudorotaxanes with a dibenzo-24-crown-8 ether wheel.
