Substituted hydroquinones, 1,4-quinones, catechols, 1,2-quinones, anthraquinones, and anthrahydroquinones are disclosed herein. The substituted hydroquinones and catechols have the formula: while the substituted 1,4-quinones or 1,2-have the corresponding oxidized structure (1,4- benzoquinones and 1,2-benzoquinones). One or more of R 1 , R 2 , R 3 and R 4 include a sulfonate moiety, a sulfonimide moiety, or a phosphonate moiety, and any of R 1 , R 2 , R 3 and R4 that do not include one of these moieties include an alkyl, a cycloalkyl, a thioether, a sulfoxide, a sulfone, a haloalkyl, a halogen, a nitrile, an imide, a pyrazole, or combinations thereof. The substituted anthraquinones have the formula: while the substituted anthrahydroquinones have the corresponding reduced structure. One or more of R 1 -R 8 have a sulfonate or phosphate tethered to the ring by a thi other, amine, or ether including one or more alkyl groups. Any of R1-R8 that do not contain one of these moieties include an alkyl, a cycloalkyl, a thiother, a sulfoxide, a sulfone, a haloalkyl, a halogen, a hydroxyl, an alkoxyl, an ether, an amine, or hydrogen The substituted hydroquinones, 1,4-quinones, catechols, 1,2-quinones, anthraquinones, or anthrahydroquinones are soluble in water, stable in aqueous acid solutions, and have useful reduction potentials in the oxidized form. Accordingly, they can be used as redox mediators in emerging technologies, such as in mediated fuel cells or organic-mediator flow batteries.

PCT No. PCT/FR93/00167 Sec. 371 Date Mar. 8, 1994 Sec. 102(e) Date Mar. 8, 1994 PCT Filed Feb. 19, 1993 PCT Pub. No. WO93/16988 PCT Pub. Date Sep. 2, 1993.The invention relates to monomers derived from perhalogenated sultones, to a process for their preparation, to the polymers obtained from the said monomers and to their use for the production of ion-conductive materials. The monomers are compounds corresponding to the formula A-CFX-SO2Z in which A denotes one groups [sic] R3-O-CF2- or R3- or R1R2N-CO-; Z denotes F, Cl, -OSi(CH3)3 or an ionic group, Z being other than F when A denotes R3-O-CF2- or R3-; X denotes F, Cl, H or RF, X being RF when A denotes R3-; the radicals R1, R2 and R3 are chosen from polymerizable nonperfluorinated organic radicals; RF is chosen from perfluoroalkyl radicals and perfluoroaryl radicals. The polymers obtained from these monomers can be employed for the production of ion-conductive materials.
