Abstract

The data on the synthesis and electrochemical properties of 2,5-disubstituted derivatives of 1,4-bis(4,5-diphenyldimidazol-2-yl)benzene are reported. The effect of substituents on redox properties has been comprehensively investigated. The electrochemical reduction of quinones into the biradical occurs at positive potentials and is a result of two stages of single-electron transfer, through the stage of the monoradical formation. The correlation between the reduction potentials and the salts structure has been found.

摘要

报道了关于1，4-双（4，5-二苯基二咪唑-2-基）苯的2，5-二取代衍生物的合成和电化学性质的数据。已经全面研究了取代基对氧化还原性质的影响。醌向双自由基的电化学还原是在正电势下发生的，这是通过单自由基形成阶段的两个单电子转移阶段的结果。已经发现还原电位和盐结构之间的相关性。
