Abstract in another language

We present organic field effect transistors (OFETs) based on solution-processable n-type polymers containing perylene bisimide as pendant groups. The OFET characteristics of a diblock copolymer consisting of polystyrene and poly(perylene acrylate) (PPerAcr) blocks and a PPerAcr homopolymer are compared. Thermal annealing improves the OFET performance by two to three orders of magnitude, which can be attributed to the improved order and interface properties in the transport layer, arising from the better alignment of the perylene bisimide moieties. Both polymers show excellent n-type performances with electron carrier mobility of 1.2×10−3 cm2/V s and low threshold voltages of 4-7 V.
