“…These reactions at nitrogen can significantly alter the optical and electrical properties of the polymers. 23,24,29,30 Despite these advantages, the pyridines as building blocks of high-performance semiconducting polymers have been restricted to a few examples so far, especially, focusing on the pyridine-flanked diketopyrrolopyrrole (PyDPP) type polymers. 10,12,[31][32][33][34][35] Polymers with high charge carrier mobility in organic electronic devices usually have planar structures and extended p-electron delocalization.…”
