Organic field‐effect transistors (OFETs) based on interconnected nanowire networks of P3HT have been successfully fabricated by using a mixed‐solvent method. The nanowire network density can be tuned by controlling the anisole/chlorobenzene ratio of mixed solvents. The obtained field‐effect mobility, threshold voltage and the ratio of on‐state current and off‐state current ( I on / I off ) was 0.0435 cm 2 /V s, –10 V and 1.75 × 10 4 , respectively. The three‐dimensional and interconnected nanowire structure of the networks can enhance the charge transport in P3HT.(© 2014 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
