Abstract Diketopyrrolopyrrole (DPP)‐based polymer semiconductors have drawn great attention in the field of organic electronics due to planar structure, decent solubilizing capability, and high crystallinity. However, electron‐deficient capacity DPP derivatives are not strong enough, leading relatively high‐lying lowest unoccupied molecular orbital (LUMO) energy levels corresponding polymers. As a result, n‐type ambipolar DPP‐based polymers rare their electron mobilities also lag far behind p‐type counterparts, which limits development important p‐n‐junction‐based electronic devices. Therefore, new design strategies been proposed recent years develop n‐type/ambipolar with improved performances. In this view, these summarized, including copolymerization different acceptors weak donors, flanked aromatic ring modification, DPP‐core expansion dimerization. The relationship between chemical structures thin‐film transistor performances is intensively discussed. Finally, perspective on future trends proposed.

Abstract Solid‐state molecular arrangement has been recognized as the most important role in charge transport properties of organic semiconductors. Although highly ordered stacking is achieved single crystals, maintaining single‐crystal packing solution‐processed thin films remains a significant challenge. Herein, new type n‐type semiconductors based on an asymmetric fluoranthene imide unit reported, whose intermolecular and aggregation behavior film state can be effectively controlled by regulating cyano substitution sites alkyl chain types group. F10 with groups at 4,9‐sites branched 2‐ethylhexyl encouragingly shows single‐crystal‐like after thermal annealing, thus resulting field‐effect transistors exhibit impressive performance, electron mobility high 0.116 cm 2 V −1 s . This work opens avenue for developing high‐performance
