Open-shell Poly(3,4-dioxythiophene) Radical for Highly Efficient Photothermal Conversion.

ABSTRACT: Open-shell organic radical semiconductor materials have received increasing attention in recent years due to their distinctive properties compared to the traditional materials with closed-shell singlet ground state. However, their poor chemical and photothermal stability in ambient conditions remains a significant challenge, primarily owing to their high reactivity with oxygen. Herein, a novel open-shell poly(3,4-dioxythiophene) radical PTTO₂ is designed and readily synthesized for the first time using low-cost raw material via a straightforward BBr₃-demethylation of the copolymer PTTOMe₂ precursor. The open-shell character of PTTO₂ is carefully studied and confirmed via the signal-silent ¹H nuclear magnetic resonance spectrum, highly
