Abstract:Conducting polymers, despite their promising electrochromic properties, face limitations in smart windows due to their inverse modulation in visible and near-infrared (NIR) regions. In this study, we introduce novel "black-to-black" electrochromic copolymers, synthesized through direct arylation polymerization (DArP) of tris(thienothiophene) (TTT), 3,4dialkylthiophene (DKTh), and benzo[c][1,2,5]thiadiazole (Tz) monomers. These copolymers demonstrate minimal visible impact (<5%) and broad NIR modulation (>60%).… Show more
