Abstract
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.
