Accompanying Structural Transformations in Polarity Switching of Heavily Doped Conjugated Polymers.

ABSTRACT: Despite significant recent advancements in highly functional organic semiconductors (OSCs), the n-type OSCs reported to date lag behind their p-type counterparts in terms of long-term environmental stability. As an alternative approach to n-type materials, a few p-type polymers have been shown to undergo dramatic transitions in their charge carrier polarity to n-type through transition metal-incorporated Lewis acid doping. Although the concept of polarity switching is promising, its unclear chemical origin-particularly from a materials science perspective-limits its potential as an n-type counterpart. In this work, the chemical and structural mechanisms underlying the p-to-n polarity switching in a heavily doped conjugated polymer are elucidated. Using gold(III) chloride-doped indacenodith
