Largely π-Extended Thienoacenes with Internal Thieno[3,2-b]thiophene Substructures: Synthesis, Characterization, and Organic Field-Effect Transistor Applications
摘要:
Two largely pi-extended thienoacenes with internal thieno[3,2-b]thiophene substructures, i.e., bis[1]benzothieno[2,3-d,2',3'-d]benzo[1,2-b;4,5-b']dithiophene (BBTBDT) and bis(naphtho[2,3-b]thieno)[2,3-d;2',3'-d]benzo[1,2-b;4,5-b']dithiophene (BNTBDT), were synthesized, characterized, and evaluated as an active layer in thin-film organic field-effect transistors.
