Density, viscosity, conductance, dye solubility, and carbon-13 n.m.r. studies were performed in aqueous solution of three disodium 4-alkyl 3-sulfonatosuccinate surfactants at 25.0�C. The CMC values were 0.33 mol dm-3 for the hexyl homologue (dhss), 0.14 mol dm-3 for the octyl homologue(doss), and 0.041 mol dm-3 for the decyl homologue (ddss). The aggregation numbers determined viscometrically and conductimetrically were 15 for dhss, 29 for doss, and 50 for ddss. The volume changes upon micellization were 7.0 cm3 mol-1 for dhss, 8.8 cm-3 mol-1 for doss, and 9.1 cm3 mol-1for ddss. Binding constants for the dye pada to the micelle and the fractions of unbound counter-ion were also obtained. The two polar heads with their carbon linkage were likely in an aqueous environment in the doss micelles with the micelles themselves being spherical.

Viscosity, conductivity, density, and fluorescence quenching studies were conducted in aqueous micellar solutions at 25.0 °C of sodium alkyl sulfoacetates and sodium dialkyl sulfosuccinates in a comparison of one-tailed and two-tailed surfactant systems. The hexyl, octyl, and decyl members of the former group and the dihexyl and dioctyl members of the latter group were investigated. The results indicated that the sulfoacetates most likely form spherical micelles with aggregation numbers 20 for hexyl, 42 for octyl, and 70 for decyl with three methods for size determination giving concordant results. For the sulfosuccinates, the aggregation numbers from fluorescence quenching were 38 for the dihexyl and 56 for the dioctyl in agreement with the results from the conductance technique which means that spherical micelles are likely formed also. Volume changes on micellization were obtained for the sulfoacetates.

For the progress of synthetic supramolecular chemistry in aqueous solution the design of host molecules soluble in this medium is essential. A possible route is the introduction of ionic residues,...
