A quaternized anthraquinone derivative for pH-neutral aqueous organic redox flow batteries

A water-soluble redox-active molecule, 2,2′-((9,10-dioxo-9,10-dihydroanthracene-1,4-diyl)bis(azanediyl))bis( N , N , N -trimethylethan-1-aminium)dichloride (BDEAQCl 2 ), was achieved that can serve as an anolyte material for pH-neutral aqueous organic RFBs.
