摘　　要：Recent advances in organic electronics of novel materials and optoelectronic devices spark great interest in the design and synthesis of high-performance polymer semiconductors. During the last decade, isoindigo(ⅡD) and its derivatives have sprung up as common electron-deficient building blocks and obtained extensive applications in organic field-effect transistors(OFETs).In this review, we first present the current status, basic principles, and general material design strategies for OFETs. Then,multiple ⅡD-type acceptors, mature synthetic routes to monomers, and typical ⅡDs-based conjugated polymers are summarized.We also introduce side-chain engineering and cutting-edge applications, like stretchable transistors, sensing, active-matrix driving, etc., of the classic copolymer poly(isoindigo-co-bithiophene). Green polymerization approaches towards conjugated polymers incorporating ⅡDs are subsequently discussed for efficient polymerization. Finally, we conclude this review and propose in-depth prospects with respect to material synthesis and device applications. Undoubtedly, ⅡDs-based conjugated polymers would occupy a significant position in the future of organic electronics, due to diverse building blocks, mature synthetic pathways, tunable side chains, and unique optoelectronic properties.
