Abstract
Potentials of the reduction of gamma-pyrilocyanines, their heteroanalogues, and flavilium dyes on a mercury film electrode and potentials of their oxidation on a glassy-carbon electrode in nonaqueous media are obtained for the first time ever by a voltammetry method. It is shown that the oxidation and reduction potentials depend on the dye molecule structure, in particular, on the nature of the heteroatom in the heterocycle. It is established that the ClO −4 anion and complex anions InCl −4 and TlCl −4 , which enter the composition of cationic flavilium dyes, undergo neither reduction nor oxidation in the potential region studied.
