High field‐effect mobilities from diblock copolymers of regioregular poly(3‐hexylthiophene) and poly(methyl acrylate) (PMA) are reported. The mobilities are achieved at several PMA contents provided the SiO 2 surface is treated with octyltrichlorosilane. The mobility decreases with increasing PMA content when the SiO 2 surface is untreated. These results show the importance of self‐assembly at the interface for good FET performance in bottom‐contact FET devices.
