Abstract
The polymer plating of 6-substituted groups-1,3,5-triazine-2,4-dithiol on metal electrodes in organic solvents was studied with respect to the effect of triazine dithiols, metal electrodes, and organic solvents on electrochemi-cal reactions. Cyclic voltammograms of 6-dioctylamino-1,3,5-triazine-2,4-dithiol (DO) on Pt plate in an acetonitrile solution of tetrabutyl ammonium hexafluoro phosphate revealed three peaks due to oxidation and reduction. The substituted groups in triazine dithiols were found to have a large influence on the reaction in polymer plating as well as their dissociation constant and oxidation potential. The type of metal electrodes was also found to affect the reactions significantly, attributable to differences in oxidation potential. Solvents accelerated the formation of radical cations for DO and bithiyl radicals for DO monosodium salt. As an overall mechanism, it was determined that thin polymer film is formed by the coupling of radical cations formed by electrochemical reaction of DO.
