Hall effect and slightly negative temperature dependence of the mobility in polymeric transistors are demonstrated. The semiconductor channel is based on a polycyclopentadithiophene‐benzothiadiazole (CDT‐BTZ) donor‐acceptor copolymer film whose chain direction is oriented by mechanical compression at the surface of an ionic liquid. The mobility is 5.6 cm 2 V −1 s −1 at room temperature, and is further improved to 6.7 cm 2 V −1 s −1 at 260 K.
