摘要: Interactions of dianionic dye, eosin yellow, with gemini pyridinium surfactants, 1,1′-(2-hydroxypropane-1,3-diyl)bis(3-(tetradecyloxy)pyridin-1-ium) bromide [14-3(OH)-14] and 1,1′-(2-hydroxypropane-1,3-diyl)bis(3-(hexadecyloxy)pyridin-1-ium) [16-3(OH)-16], have been investigated using conductivity, UV-visible, fluorescence, cyclic voltammetry, differential pulse potentiometry dynamic light scattering techniques. Micellar, thermodynamic electrochemical parameters evaluated conductivity voltammetry. The critical micelle concentration both the surfactants decreases in presence dye. formation dye-surfactant ion-pairs premicellar dye–surfactant aggregates sub-micellar region has observed their stoichiometry was determined UV-visible Dynamic measurements provided information regarding size pre- post-micellar absence Quantitative evaluation interactions among dye done terms quenching binding voltammetry
