Thienoacene dimers based on the thieno[3,2-b]thiophene moiety: Synthesis, characterization and electronic properties

Abstract

Two thienoacene dimers based on the thieno[3,2-b]thiophene moiety were efficiently synthesized, characterized and evaluated as active hole-transporting layers in organic thin-film field-effect transistors. Both compounds behaved as active p-channel organic semi-conductors showing averaged hole mobility of up to 1.33 cm2 V-1 s-1.
