A new n-type semiconductor family for organic field-effect transistors (FETs), based on core-unsubstituted and core-cyanated anthracenedicarboximides, is reported. By tuning electron affinity, these materials exhibit good electron-transport properties and stability in ambient as well as very high Ion/Ioff ratios. Unoptimized N,N-di-n-octyl-9,10-dicyano-2,3:6,7-anthracenedicarboximide (ADI8-CN2)-based FETs exhibit good electron mobilities (μe = 0.02 cm2/(V s)) and very high Ion/Ioff > 107 in ambient conditions.
