thermal stability, and solution processability, the resulting polyimide films exhibited ambipolar electrochromic behavior. The nonconjugated TPA-based polyimides III revealed more stable electrochemical oxidation behavior and better electrochromic reversibility than conjugated DPA-based corresponding polyimides I due to the additional phenyl ring providing the route to stabilize the cationradical formed
