• Aromatic diimides have attracted much attention due to their unique properties and potential applications for n-channel organic field effect transistors (OFETs). In this study, N,N'-dialkyl-6,13-dicyano pentacene-2,3:9,10-bis(dicarboximide) (1) was synthesized and used in n-channel OFETs. The photophysical, electrochemical and thermal properties of 1 were investigated. The low LUMO energy level (-4.15 eV) located within the air stability window ensures air-stable n-channel operation. Solution-processed top-contact thin film transistors based on such linear aromatic dicarboximide showed typical n-channel characteristics with a high electron mobility of up to 0.08 cm super(2) V super(-1) s super(-1) and a high I sub(on)/I sub(off) ratio of 10 super(6) to 10 super(7). The devices exhibited good air stability when exposed to air for several months. Complementary inverters based on n-type 1 and p-type TIPS-pentacene were fabricated, which showed a maximum voltage gain (-dV sub(OUT)/dV sub(IN)) of 57.
