Here we report a novel twisted monomer based on a distorted CC double bond for lowbandgapconjugated copolymers. This new buildingblock provides several unique characteristics when compared to classical planar systems such as high solubility, electron accepting ability, and isomeric tunability. The resulting copolymers exhibit broad absorption spanning both visible and near‐infrared regions leading
