Description
Isabelle Heinzen and co-authors build in 2026 a family of conducting polymers decorated with ring shaped crown ether groups and map how the decoration trades order against ion flow. Five versions of the polymer PEDOT carried crown ether shares from none to all of their side chains. These mixed conductors, which move both electrons and ions, underpin bioelectronic devices that must dope and undope quickly in salty fluids.
More crown ether sharpened electronic delocalization and nanoscale order, yet the structure compacted, pores shrank, and ions moved worse. The voltage window for doping narrowed, and the salt anion, not the sodium cation the rings were meant to catch, set the doping onset. A half decorated version won overall, pairing the highest charge storage with fast switching. In chloride solutions its doping ignored film thickness, a plus for scaling.
