Air-stable material for vacuum or liquid-processed n-type organic field-effect transistors is easily synthesized by cyano-substitutions on para and ortho positions versus nitrogen of soluble triphenodioxazines. This regioisomer promotes favorable molecular packing while increasing the electron affinity. Without encapsulation and after 30 days, the performances of devices remain high under air measurement conditions.
