摘要: Three thiadiazoloquinoxaline-containing long pyrene-fused N-heteroacenes with 8, 13, and 18 rings were designed synthesized. They show high electron affinities (EAs) of approximately 4.1 eV, which derived from the onset reduction peaks in cyclic voltammetry. Crystal structure analysis revealed in-plane extension through close contacts between thiadiazole units as well layered packing, enabling interlayer transport. Organic field-effect transistor devices provided mobilities, suggest a potential way to enhance charge transport N-heteroacenes.
