Abstract:
Disclosed are new semiconductor materials prepared from rylene-(π-acceptor) copolymers. Such copolymers can exhibit high n-type carrier mobility and/or good current modulation characteristics. In addition, the polymers of the present teachings can possess certain processing advantages such as solution-processability and/or good stability at ambient conditions.

Specifically, the enantiomerically enriched mixture has unexpected electron-transport efficiency compared to the racemate or either of the enantiomers in optically pure form.
Abstract:
Disclosed is a method for preparing an organic electronic device, which contains one or more layers of a suitable functional material on a substrate, which process is characterized in that at least one interlayer of an amphiphilic protein is placed between adjacent layers of the functional material, or between the substrate and the adjacent layer of the functional material. The protein interlayer improves the adhesion of layers without negative impact on the device's performance.
Abstract:
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.
Abstract:
A method for depositing a semiconducting layer comprising: a) providing a substrate having a surface; b) providing a mixture comprising one or more semiconducting compounds and one or more polymeric insulating compounds in a liquid; c) bringing at least part of the surface into contact with the mixture; d) moving a zone of the mixture being in contact with the surface along the surface in a moving direction, said zone providing a concentration gradient in the moving direction by evaporating at least part of the solvent; and e) if necessary, removing the non-evaporated part of the solvent.
