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

초록

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 cm2V-1s-1.
