Abstract

We describe ion current rectification using a Polymer of Intrinsic Microporosity (PIM) based on Tröger's base (PIM-EA-TB). When deposited asymmetrically over one (or more) 20 μm diameter hole(s) in 6 μm thick poly(ethylene terephthalate) and investigated in a two-compartment electrochemical cell with acidified aqueous NaCl on both sides, novel ionic diode effects are observed.
