A facile top‐pining controlled dewetting strategy is developed to fabricate patterned polymeric 1D micro/nanostructures. Large‐scaled polymer‐poly[4‐(4,4‐dihexadecyl‐4H‐cyclopenta[1,2‐b:5,4‐b′]dithiophen‐2‐yl)‐alt‐[1,2,5] [3,4‐c]pyridine] microwire arrays with mobility up to 29.0 cm 2 V −1 s −1 are fabricated. The devices show excellent electrical stability in ambient conditions. This work paves the way for fabricating large‐area, high‐performance, and low‐cost 1D micro/nanostructures in organic field‐effect transistors and other electronic devices.
