摘要：
A phthalimide-containing redox-active polymer is designed and synthesized in particular for the application in all-organic redox-flow batteries. 4-Vinylbenzyl phthalimide is prepared in a one-step reaction and copolymerized with a solubility promoting comonomer. The novel polymer is electrochemically characterized in various electrolytes via cyclic voltammetry and features a quasireversible reduction reaction at E-1/2(0) = -1.89 V versus AgNO3/Ag. Afterward, the polymer is applied as anode-active material in a first preliminary battery test in combination with a 2,2,6,6-tetramethylpiperdinyl-N-oxyl-containing polymer as cathode-active material and a porous membrane as separator, yielding a polymer-based all-organic battery system with a high cell voltage of 2.0 V.
