Using a complex of physicochemical methods it has been shown for the first time that the diluted solutions  (10-11–10-3 М) of dodecyl derivative of p-sulfonatocalix[6]arene are disperse systems, where the role of a disperse phase is played by the supramolecular structures of different nature – micelles (above 6·10-4 М), domains (1·10-4–1·10-7 М)  and nanoassociates (1·10-9–1·10-8 М). The disperse phase’s parameters change nonmonotonically as systems dilution, what results in the decrease of surface tension at concentrations lower than the critical micelle concentration and determines the differences in systems’ behaviour at various temperatures (15–60 °C) and hold up times (after 8 months).
