By using a microwave assisted Schiff-base condensation reaction between triquinoyl and 1,2-diaminobenzene, we synthesize a water-insoluble fused phenazine derivative, hexaazatrinaphtylene (HATN), and study its electrochemical performance against a ferrocyanide catholyte in an alkaline aqueous hybrid flow battery. Reversible two-step three-electron transfers and rapid surface-controlled redox reaction kinetics are observed for the HATN electrode in alkaline aqueous solution. Compared to previously-reported organic anode materials for aqueous hybrid flow battery, the HATN exhibits greatly enhanced specific capacity and comparable efficiency and cycling stability.
