The influence of anionic surfactant, sodium dodecyl sulphate (SDS), and cationic one, cetylpyridinium bromide (CPB), on aggregation behavior of squaraine dye Sq-2Me has been studied in aqueous solutions by optical spectroscopy. It has been found that the addition of surfactants at concentrations hig...
