Supramolecular chirality largely modulates chemical doping of conjugated polymers.

ABSTRACT: Chemical doping has unlocked the touted potential of conjugated polymers by significantly boosting their conductivity and device performance. Yet, the relationship between doping and the polymers' complex, multiscale morphology remains elusive. Herein, we report a surprising find that supramolecular chirality, which up to now had not been considered a parameter relevant to doping, significantly boosts the underpinning redox reaction in conjugated polymer thin films. The chiral helical structures arise during an evaporative assembly process upon meniscus-guided coating, when the originally racemic conjugated polymer chains aggregate first and assemble into chiral twist-bent nematic mesophases which "imprint" their solution-state structure into solid thin films.
