Novel Diketopyrroloppyrrole Random Copolymers: High Charge‐Carrier Mobility From Environmentally Benign Processing

The random copolymerization between two different diketopyrrolopyrole-based conducting units represents a suitable synthetic strategy to increase the solubility of polymer semiconductors in a non-chlorinated solvent, without compromising the high charge-carrier mobility. Highly performing thin-film transistors processed from environmentally benign solvents such as tetralin are demonstrated for the first time, resulting in a mobility of greater than 5 cm2 V−1 s−1.
