摘要：

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.
