Organic materials are emerging for the pseudocapacitors as they offer high theoretical redox capacitance and can be derived from the renewable sources. They are composed of non-metals, resulting in light weight, flexible, and potentially low-cost devices. While there are hundreds of commercial organic molecules available and nearly unlimited can be synthesized, only a handful of them are suitable for the pseudocapacitive applications. Therefore, the discovery of innovative organic materials beyond conventional pseudocapacitive organic materials (e.g. quinones, conducting polymers, etc.) is much needed for the sustainable pseudocapacitors. Here, for the first time, we report quinone-functionalized viologen molecules as a high capacitance/rate pseudocapacitive organic electrode material on hybridization with reduced graphene oxide sheets. Given the reliable pseudocapacitance of quinone-functionalized viologen-based hybrids under positive potentials, optimized electrodes were paired with two-dimensional titanium carbide (Ti₃C₂T_x) MXene as negative electrodes to manufacture multi-electron redox asymmetric supercapacitors. The resulting full devices were capable to store charge within enlarged voltage window up to 1.5 V in 3 M H₂SO₄. In addition, these devices exhibited ultrahigh rate performance (~77% capacitance retention from 10 to 1,000 mV/s), energy density (~20 Wh/kg), and capacitance retention of 80% after 10,000 charge/discharge cycles.

伪电容器正在出现有机材料，因为它们具有较高的理论氧化还原电容，并且可以从可再生资源中提取。它们由非金属组成，因此重量轻，柔性大，成本低。尽管有成百上千种可商购的有机分子，并且几乎可以无限合成，但是其中只有少数适​​用于准电容应用。因此，对于可持续的伪电容器来说，急需发现超越常规伪电容有机材料（例如醌，导电聚合物等）的创新有机材料。在这里，我们首次报道了与还原的氧化石墨烯片杂交时，醌官能化的紫精分子作为高电容/倍率假电容有机电极材料。₃ C ₂ T _x）MXene作为负极来制造多电子氧化还原不对称超级电容器。所得的完整器件能够在3 MH ₂ SO _4中的高达1.5 V的扩大电压窗口内存储电荷。此外，这些器件在10,000次充电/放电循环后表现出超高倍率性能（从10到1,000 mV / s，约77％的电容保持率），能量密度（约20 Wh / kg）和80％的电容保持率。
