Here we report a novel twisted monomer based on a distorted C=C double bond for low bandgap conjugated copolymers. This new building block 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 to promising solar cell performance. A simplified synthetic approach provided novel building blocks for conjugated polymers featuring a non-planar repeat unit and a distorted double bond. The resulting copolymers are characterized by a broad absorption profile and show promising results in solar cells.
