Air‐Stable and High‐Mobility n‐Channel Organic Transistors Based on Small‐Molecule/Polymer Semiconducting Blends

Abstract

Use of a carefully designed small-molecule organic semiconductor based on an oxidized diketopyrrolopyrrole core enables the fabrication by solution processing of electron-transporting (n-channel) blend-based organic thin-film transistors with high electron mobility (0.5 cm(2)/Vs) and high operating stability even when the devices are exposed to ambient air for prolonged periods of time.
