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

Authors


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 cm2/Vs) and high operating stability even when the devices are exposed to ambient air for prolonged periods of time.
