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 R1, R2, R3 and R4 include a sulfonate moiety, a sulfonimide moiety, or a phosphonate moiety, and any of R1, R2, R3 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 R1-R8 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.
本文披露了取代的对苯二酚、1,4-喹啉醌、邻苯二酚、1,2-喹啉醌、蒽醌和蒽氢醌。取代的对苯二酚和邻苯二酚的化学式为:而取代的1,4-喹啉醌或1,2-喹啉醌具有相应的氧化结构(1,4-苯醌和1,2-苯醌)。R1、R2、R3和R4中的一个或多个包括磺酸酯基、磺酰胺基或膦酸酯基,而不包括这些基团之一的R1、R2、R3和R4包括烷基、环烷基、硫醚、亚硫醚、砜、卤代烷基、卤素、腈、酰亚胺、吡唑或其组合。取代的蒽醌的化学式为:而取代的蒽氢醌具有相应的还原结构。R1-R8中的一个或多个通过硫醚、胺或醚与环相连,包括一个或多个烷基。不含这些基团之一的R1-R8包括烷基、环烷基、硫醚、亚硫醚、砜、卤代烷基、卤素、羟基、烷氧基、醚、胺或氢的任何基团。取代的对苯二酚、1,4-喹啉醌、邻苯二酚、1,2-喹啉醌、蒽醌或蒽氢醌在水中溶解,在水酸性溶液中稳定,并且在氧化形式中具有有用的还原电位。因此,它们可以用作新兴技术中的氧化还原中介体,例如在介导燃料电池或有机介质流动电池中。
