  • SEMICONDUCTOR MATERIALS PREPARED FROM DITHIENYLVINYLENE COPOLYMERS
    Publication number: 20120217482
    Abstract: Disclosed are new semiconductor materials prepared from dithienylvinylene copolymers with aromatic or heteroaromatic ?-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.
