A highly rigid amine-based polymer of intrinsic microporosity (PIM), prepared by a polymerization reaction involving the formation of Tröger's base, is demonstrated to act as an ionic diode with electrolyte-dependent bistable switchable states. Ionic flip-flop: Polymers with intrinsic microporosity introduce ionic diode and metastable switching effects as a result of their rigid backbone and molecular-structure-dependent anion versus cation conductivity.
