n-Channel polymer field-effect transistor (FET) devices are fabricated via a simple coating process using a suspension containing thermally stable nanowires prepared from a new perylene diimide polymer. The devices show excellent performance with remarkably high average electron mobilities, high on/off ratios, low threshold voltages, and negligible hysteresis. These properties are attributed to the formation of nanowires and ordered phases with a high degree of molecular ordering and a preferential orientation within the active polymer layer. This may lead to the low-cost mass production of high-performance n-channel FET devices.
