In recent years, conjugated polymers have received widespread attention due to their characteristic advantages of light weight, favorable solution processability and structural modifiability. Among various conjugated polymers, fluorinated ones have developed rapidly to achieve high‐performance n‐type or ambipolar polymeric semiconductors. The uniqueness of fluorinated conjugated polymers contains the high coplanarity of their structures, lower frontier molecular orbital energy levels and strong non‐bonding interactions. In this review, we first summarize the fluorinated building blocks, including fluorinated benzene and thiophene rings, fluorinated B←N bridged units, and fluoroalkyl side chains. Subsequently, different synthetic methods of fluorinated conjugated polymers are described, with a special focus on their respective advantages and disadvantages. Then, with these numerous fluorinated structures and appropriate synthetic methods bear in mind, we systematically discuss the properties and applications of the fluorinated conjugated polymers, such as cyclopentadithiophene‐, amide‐, and imide‐based polymers, and B←N embedded polymers. The introduction of fluorine atoms can further enhance the electron‐deficiency of the backbone, influencing the charge carrier transport performance. The promising fluorinated conjugated polymers were applied widely in organic field−effect transistors, organic solar cells, organic thermoelectric devices, and other organic opto‐electric devices. Finally, we present our outlook on the challenges and future development of fluorinated conjugated polymers.This article is protected by copyright. All rights reserved
