Role of amphiphilic surfactant in electrochemical and spectroscopic behavior of p-nitrophenoxyalkyl ammonium salts

Previously published results concerning electrochemical reductions in the presence of amphiphilic surfactants report two phenomena: potential shift and decrease in intensity of polarographic waves. The electrochemical and spectroscopic behavior of p-nitrophenoxyalkyl ammonium salts [Display omitted] shows that the former is related to adsorption of surfactant molecules while the latter arises from micelle formation. Polarographic and spectroscopic data analysis is consistent with a bent conformation of the electroactive ammonium salt molecules in the double layer and micelles.
