Disclosed are new semiconductor materials prepared from dithienylvinylene copolymers with aromatic or heteroaromatic π-conjugated systems. Such copolymers, with little or no post-deposition heat treatment, can exhibit high charge carrier mobility and/or good current modulation characteristics. In addition, the polymers of the present teachings can possess certain processing advantages such as improved solution-processability and low annealing temperature.

and characterization of thienylenevinylene-based donor–acceptor alternating copolymers (PTVPhI-Eh and PTVPhI-C12) as highlyefficientambipolar semiconductors in a thin film transistor. These polymers exhibit significantly improved hole and electron mobilities after thermal annealing. To determine the relationship between ambipolarchargetransport and thermal annealing, we investigated these polymers

An efficient Pd and Cu co-catalyzed DArP was developed via inert C−Sbond cleavage of aryl thioethers. Moreover, the mechanism studies highlighted the important role of palladium (Pd) and copper (Cu) co-catalysis. Of note, CPs synthesized in this method possessed low trap densities, high Mns and charge transport mobility, signifying an excellent choice for synthesizing high performance CPs.
通过芳基硫醚的惰性 C−S 键断裂开发了一种高效的 Pd 和 Cu 共催化 DArP。此外,机理研究强调了钯(Pd)和铜(Cu)共催化的重要作用。值得注意的是,该方法合成的CP具有低陷阱密度、高M n s和电荷传输迁移率,是合成高性能CP的绝佳选择。
