Functionalization of poly(4-chloromethylstyrene) with anthraquinone pendants for organic anode-active materials†

摘要: Condensation of anthraquinone-2-carboxylic acid with poly(4-chloromethylstyrene) afforded a high-density redox polymer containing the anthraquinone pendants reversible charge storage capability at negative potentials near −1 V versus Ag/AgCl. Electrochemically response polymer, which was ascribed to reduction pendant group anion radical and dianion, suggested that sufficiently robust in these states for application. Immobilizing groups on current collectors accomplished by use swellable yet insoluble both aqueous nonaqueous electrolyte solutions. Such properties allowed accommodation external cations from solution permeate through layer electroneutralization produced reduced state, led repeatable charging discharging cycles without degradation capacity. Exploration electrochemistry anthraquinone, had been inaccessible lack solubility conjugated fused-ring molecule H2O, became feasible virtue swelling property electrolyte. While relatively difficult be stored polymers compared positive due enhanced reactivity their small varieties appropriate sites, present characterized as excellent organic electrode-active materials operated essential fabrication entirely batteries.
