The azomethine TPA-(BTZ)3-TPA with a donor–acceptor–acceptor–acceptor–donor structure has been synthesized and characterized. Azomethine exhibited luminescence properties positive solvatochromic effect. Electropolymerization on terminated triphenylamine groups was used to obtain thin layer of the polyazomethine poly-[TPA-(BTZ)3-TPA]. Further investigation oxidation/reduction poly-[TPA-(BTZ)3-TPA] via cyclic voltammetry showed that polymer undergoes two reversible processes due presence tetraphenylbenzidine moieties. Electrochromic were investigated spectroelectrochemistry. It observed in its neutral state is orange, color changes green upon electro-oxidation. stability during multiple cycles, response times, coloration efficiency also investigated.

An electroactive coating functionalized with carbonyls could undergo reversible covalent bond formation various amines. Hydrolyzing the coating's azomethine released carbonyl, and it subsequently be condensed a different amine. The heteroatomic also sustain dynamic exchange by replacing its constitutional amine discrete oxidation potentials emissions of products were used to confirm electrochemically spectroscopically. Reversibly modifying both electroactivity emission courtesy opens possibility perpetually adjusting properties degraded coatings. Ultimately, can extend lifetime films improve their life cycle management repurposing them for uses.
