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.
