Anthracenedicarboximides as air-stable n-channel semiconductors for thin-film transistors with remarkable current on-off ratios

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 I (on)/I (off) ratios. Unoptimized N,N '-di-fD ctyl-9,10-dicyano-2,3:6,7- anthracenedicarboximide (ADI8-CN2)-based FETs exhibit good electron mobilities (f(e) = 0.02 cm(2)/(V s)) and very high I (on)/I (off) > 10(7) in ambient conditions.
