|Abstract:||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 cm2 V-1 s-1 and a high I on/Ioff ratio of 106 to 107. 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 (-dVOUT/dV IN) of 57. © The Royal Society of Chemistry 2013.|
