Field-Effect Transistors Based on a Benzothiadiazole−Cyclopentadithiophene Copolymer

Abstract

We present a solution processed organic field-effect transistor based on a benzothiadiazole (BTZ)−cyclopentadithiophene (CDT) copolymer with mobilities as high as 0.17 cm2/Vs and an on/off ratio of 105. This pronounced performance together with the lack of macroscopic order in the thin film makes this conjugated copolymer an attractive candidate for low-cost organic electronics due to its facile processing.
