(a) Spectroelectrochemistry of PEDOTF8 (M n = 70200) film. (b,c) Square-wave potential step absorptiometry of PEDOTF8 devices in the visible and near infrared regions between 0.0 and 1.3 V with a switching time of 15 s. Black line: 430 nm. Red line: 650 nm. Blue line: 1000 nm. (d) Colouring and bleaching processes of the polymer (M n = 70200). (e) The process of the polymer (M n = 40000). Conditions: Electrolytic solution of 0.1 M Bu4NBF4/CH3CN, Working electrode: indium-tin-oxide-coated polyethylene terephthalate, Counter electrode: Pt, Reference electrode: Ag/AgCl.
