•A new fluorine-containing, triphenylamine-based diamine monomer was synthesized.•New redox-active polyamides and polyimides with fluorotriphenylamine units were prepared.•The polymers could afford flexible and tough films with moderately high thermal stability.•The polymers are potential anodically coloring green or blue electrochromes.
Novel electroactive aromatic poly(amine-amide)s and poly(amine-imide)s with 4-fluorotriphenylamine units in the backbone were prepared from a newly synthesized diamine monomer, 4,4′-diamino-4″-fluorotriphenylamine, with aromatic dicarboxylic acids and tetracarboxylic dianhydrides via the phosphorylation technique and conventional two-step polycondensation technique, respectively. All the synthesized polymers could afford flexible and tough films with moderately high thermal stability. Cyclic voltammograms of the poly(amine-amide) and poly(amine-imide) films on the indium-tin oxide (ITO)-coated glass substrate exhibited a pair of reversible oxidation waves with oxidation half-wave potentials (E1/2) of 0.91–0.99 V and 1.19–1.23 V (vs. Ag/AgCl), respectively, in an electrolyte/acetonitrile solution. They also exhibited obvious electrochromic behavior between their neutral and oxidized states changing from pale yellow to green or blue.
