HIGH PERFORMANCE SOLUTION PROCESSABLE SEMICONDUCTING POLYMERS BASED ON ALTERNATING DONOR ACCEPTOR COPOLYMERS

摘要

to as a repeating unit comprising a group of formula I, a number average molecular weight M _n of 30 to 70 kg / mol range of benzo-thiadiazole-a cyclopentadithiophene copolymer is disclosed Formula I In the formula, R is a hexadecyl or 3,7-n-. The invention also as semiconductors or charge transport materials, as thin-film transistor (TFT), or in semiconductor components for organic light emitting diode (OLED), for photovoltaic components or in sensors, batteries within the electrode material as, as an optical wave guide or for electrophotographic applications, and the use of the copolymer. ;
