Diketopyrrolopyrrole (DPP)-based polymeric semiconductors have recently attracted widespread attention and, due to their high field-effect mobility values, been studied for the field of organic field-effect transistors (OFETs). DPP-based polymers are composed of the electron-deficient DPP and two flanking aromatic units, and have excellent electronic properties due to their main chain planarity and strong donor-acceptor intermolecular interactions. In the current review, we summarize the pathways used to synthesize DPP-based polymers, the effects of engineering the main chains and side chains of these polymers on the p-type/n-type/ambipolar semiconducting performances of OFETs made using these polymers, and applications of these OFETs as chemical sensors.
