Theoretical Aspects of the Electropolymerization of Some Hydroquinonic Derivatives
(Biointerface Research Applied Chemistry, 2021) Tkach, Volodymyr V.; Kushnir, Marta, V; de Oliveira, Silvio C.; Lystvan, Vitalii V.; Dytynchenko, Inna M.; da Silva, Adriano O.; Kormosh, Zholt O.
For the first time, the possibility of the electrochemical synthesis and polymerization of some novel modified naphthoquinone compounds has been described. The correspondent mathematical model has been analyzed by means of linear stability theory and bifurcation analysis. It has been shown that the electro organic synthesis may serve as an interesting substitution for Suzuki reaction for the synthesis of ferrocenyl naphthoquinone and its polymer. The oscillatory and monotonic instability, in this case, will be more probable than in the general electropolymerization case.
The Theoretical Description for Psilocin Electrochemical Determination Over Cobalt Oxyhydroxide
(Univ Federal Mato Grosso Sul, dept Quimica, 2023) Tkach, Volodymyr V.; Kucher, Mykhailo M.; Kushnir, Marta, V; Ivanushko, Yana G.; Akinay, Yuksel; Karakoyun, Necdet; Kormosh, Zholt O.
The possibility of psilocin electrochemical determination and electropolymerization over cobalt (III) oxyhydroxide-modified anode is evaluated from the mathematical point of view. This process may be aimed for rapid and sensitive psilocin electrochemical determination method and for psilocin conversion to a green conducting polymer composite. Psilocin is thereby oxidized yielding either micro-or macromolecular product, being both of them important for the economical and green conducting polymer composite for electrocatalysis, electroanalysis and energy conversion. The analysis of the correspondent mathematical model confirms, that, despite of the high probability of the oscillatory behavior, the electrochemical process is efficient from both analytical and synthetical point of view.[GRAPHIC]
