Chirality‐Induced Split Personality in Polymer with Intrinsic Microporosity‐Based Artificial Ion Channels

selectivity ratio of 17.6. This work introduces a multifunctional, chiral PIM-based artificial ion channel system with a "split personality" governed by its chiral constituents. It represents the first application of chiral polymers in transmembrane transport, inspiring innovative design strategies for developing polymer-based artificial ion channels.
