High-performance organic field-effect transistors based on dihexyl-substituted dibenzo[d,d′]thieno[3,2-b;4,5-b′]dithiophene†
Abstract
A novel thienoacene compound, dihexyl-substituted dibenzo[d,d′]thieno[3,2-b;4,5-b′]dithiophene (C6-DBTDT), is developed as a p-type organic semiconductor for high-performance organic field-effect transistors. Insertion of an acceptor material at the contact interface enables substantial
