A facile polymer‐matrix‐mediated molecular self‐assembly of polymer semiconductors into highly crystalline orders for efficient charge transport in organic thin‐film transistors is demonstrated. Phenomenal enhancements in field‐effect mobility of about one order of magnitude and current on/off ratio of two to three orders of magnitude are realized with polyacrylonitrile‐incorporated polymer semiconductor compositions via solution deposition.
