A novel design of electroactive components of rechargeable organic batteries based on stable verdazyl radicals bearing various substituents is proposed. 3-Positioned aromatic substituents at the verdazyl moiety affect the reduction potentials and almost do not affect the oxidation potential, while 1-positioned aromatic substituents affect contrariwise the oxidation potential of this radical without any influence on the reduction potential. The acquired electrochemical data allowed us to reveal the structure—potential relationship for the cathodic and anodic processes, which provided the design of triarylverdazyl radicals possessing record-breaking parameters of the “electrochemical gap”.

Triarylverdazyl 自由基作为可充电有机电池的有希望的氧化还原活性成分

提出了一种基于带有各种取代基的稳定 Verdazyl 自由基的可充电有机电池电活性组件的新设计。verdazyl 部分的 3 位芳香取代基影响还原电位，几乎不影响氧化电位，而 1 位芳香取代基相反影响该自由基的氧化电位，而对还原电位没有任何影响。获得的电化学数据使我们能够揭示阴极和阳极过程的结构-电位关系，这提供了具有破纪录的“电化学间隙”参数的三芳基戊二烯自由基的设计。
