“Molecule‐framework” and “side‐chain” engineering is powerful for the design of high‐performance organic semiconductors. Based on 2DQTT s, the relationship between molecular structure, film microstructure, and charge‐transport property in organic thin‐film transistors (OTFTs) is studied. 2DQTT‐ o ‐B exhibits outstanding electron mobilities of 5.2 cm 2 V –1 s –1 , which is a record for air‐stable solution‐processable n ‐channel small‐molecule OTFTs to date.
