Abstract
The incorporation of 3,6-carbazole units into photoactive copolymers results in conjugation breaks along the polymer backbones and thus in strong intermolecular interactions. Such copolymers provide thermally reproducible morphologies and enhanced device performances over a wide range of annealing temperatures, 100 to 160 °C, with high power conversion efficiencies of over 6%.
