A phthalimide-fused naphthalene diimde (NDIIC24) with a low-lying LUMO energy level (-4.21 eV) and moderate solubility was synthesized. Organic field effect transistors (OFETs) based on solution processed thin films showed typical n-channel characteristics with a high electron mobility of 0.056 cm(2) V-1 s(-1) and a high on-off current ratio of 10(5)-10(6). The devices exhibited very good air stability and operating stability. Complementary inverters based on n-type NDIIC24 and p-type TIPS-pentacene demonstrated a maximum voltage gain (-dV(OUT)/dV(IN)) of 64.
