High-Performance n-Channel Organic Thin-Film Transistor Based on Naphthalene Diimide

摘要

A conjugated molecule comprising 1,4,5,8- naphthalene diimide (NDI) substituted with two octadecyl- amine (OD) chains has been synthesized (NDI-OD2) in a single step from commercial materials, and its organic thin-film transistor (OTFT) devices on glass substrate have been studied using poly(vinyl alcohol) (PVA) gate dielectric material. Although we utilized the PVA dielectric without any intermediate buffer layer or PVA cross-linkers, excellent electron mobility as high as ~1.0 cm~2V~(-1) s~(-1) are obtained.
