Organic Field Effect Transistors Based on DNTT and Related Organic SemiconductorsHighly extended polyacenes such as pentacene and naphthacene have been essential organic semiconductors for high-performance organic field-effect transistors (OFETs). Among the range of thienoacene-based organic semiconductors, materials with an internal thieno[3,2-b]thiophene substructure, such as DNTT and BTBT, have shown
