A soluble precursor of dinaphtho[2,3‐b:2 ′ ,3 ′ ‐f]thieno[3,2‐b]thiophene (DNTT) is developed for high‐performance printed organic thin‐film transistors (OTFTs). The DNTT precursor enables excellent thin‐film formation and can induce specific phase separations when blended with inert polymers. The DNTT OTFTs processed from the precursor/polymer blend exhibit field‐effect mobilities of up to 1.1 cm 2 V −1 s −1 and excellent durability against air exposure and thermal stress.
