WebAug 20, 2024 · The structure of P3HT, its solid-state organization and its polymorphs are at the core of a long-lasting debate. It is believed that P3HT could form two polymorphs [27,36,37,38,39]. Indeed, only one of its polymorphs has been characterized, although only partially, since the fractional coordinates have not been reported. WebSep 18, 2014 · Download : Download full-size image.
