Abstract
Intrinsically microporous polyamines (PIM-EA-TB) provide tertiary amine binding sites for protons and in this way allow switching/gating from a low ionic conductivity state to semipermeable anion conductivity through micropores. In ethanolic NaClO4 media ionic conductivity in PIM-EA-TB films (approx...
