An all-organic cell comprising 2,3-dimethyl-1,4-napthoquinone and pyrano[3,2-f]chromene as electroactive elements exhibited a good combination of large cell voltage and stability of the reduced quinone upon the addition of diethyl malonate (a weak organic acid), as compared to the addition of trifluoroethanol (which led to a high cell potential but low stability via strong hydrogen bonding interactions) and the addition of trifluoroacetic acid (which led to a lower cell potential but high stability through proton transfer).
一种全有机电池，包含 2,3-二甲基-1,4-萘醌和吡喃并[3,2-f]色烯作为电活性元件，与添加三氟乙醇（通过强氢键相互作用导致高电池电势但低稳定性）和添加三氟乙酸（通过质子转移导致低电池电势但高稳定性）相比，添加二乙酯丙二酸（一种弱有机酸）可使还原醌的电池电压和稳定性得到很好的结合。
