A series of alkylated dinaphtho[2,3‐ b :2′,3′‐ f ]thieno[3,2‐ b ]thiophenes (C n ‐DNTTs) were developed as vapor‐processable organic semiconductors for organic thin‐film transistors (OTFTs). All the C n ‐DNTT‐based OTFTs showed typical p‐channel FET characteristics and among them, C 10 ‐DNTT possessing two n ‐decyl groups gave excellent FET characteristics under the ambient conditions with mobility close to 8.0 cm 2 V −1 s −1 and I on / I off > 10 8 .
