Abstract A series of copolymers containing a glycolated 1,4‐dithienyl‐2,3,5,6‐tetrafluorophenylene unit copolymerized with thiophene, bithiophene, thienothiophene and 1,2,4,5‐tetrafluorobenzene comonomer units were designed and synthesised by direct heteroarylation polymerisation. The optical, electrochemical, electrochromic and solid‐state structural properties of the copolymers were investigated. The copolymers exhibit stable redox properties in organic solvents and promising redox properties in thin film configuration with an aqueous electrolyte. Finally, the potential of the copolymers as active materials in organic electrochemical transistors (OECTs) was assessed, and promising performance was shown as an accumulation‐mode OECT material with a peak transconductance of 0.17 mS and a good on/off ratio of 10 5 for the thiophene copolymer.
