Solid-state polymerization of EDOT derivatives containing acenaphthenequinoxaline ring

The poly (8, 11-bis (3, 4-ethylenedioxythiophen-2-yl) acenaphtho 1, 2-b] quinoxaline) (PBEAQ), was synthesized by solid-state polymerization using ferric chloride (III) as an oxidant in high yield. The structure of the monomer and polymer was elucidated by FT-IR, UV-vis absorption spectrum and element analysis. PBEAQ has an η] value of 0.42 dl g^?1 at 25 °C in H₂SO₄ (w=98 %). The electrochemical performance of PBEAQ was investigated by cyclic voltammetry (CV), galvanostatic charge-discharge and electrochemical impedance spectroscopy with three-electrode cell configuration in acidic (1 M H₂SO₄), alkaline (6 M KOH) and organic (0.1 M tetraethylammoniumtetrafluoroborate (TEABF₄) acetonitrile solution) electrolytic solutions and PBEAQ exhibits good performance in acidic medium.
