“…C10, 12, 16 and 18, it was found that the intensities of the absorption bands at 554 and 400 nm increase with increasing alkyl chain length from gemini C10 to C18. This indicates an increase in the strength of the interactions with the increase of the alkyl chain length, as observed in reference [43].…”

“…4, it can be seen that the addition of gemini surfactant (12-2-12) at concentration below CMC caused a bathochromic shift of about 20-30 nm with the appearance of a short peak at 400 nm. This hyperchromic shift is characteristic of AR52 bound to cationic micelles of surfactant and the intensity of the maximum absorption band increased with increasing surfactant concentration after the CMC [43]. In submicellar regions, the dye formed a sparingly soluble precipitate which became soluble as the gemini (12-2-12) concentration reached its CMC.…”

A homologous series of new gemini cationic surfactants were synthesized and characterized using micro elemental analysis, FTIR, 1 H-NMR and mass spectra. The surface activities of these amphiphiles were determined based on the data of surface tension. Critical micelle concentration, effectiveness of the surface tension reduction, efficiency of adsorption, maximum surface excess, minimum surface area and critical packing parameter were evaluated. The effect of cationic micelles on solubilization of anionic azo dye, sulforhodamine B (Acid Red 52) in aqueous micellar solution of the synthesized gemini cationic surfactants was studied at pH 6.9 ± 0.5 and 25°C. The results showed that the solubility of dye rose with increasing surfactant concentration as a consequence of some association between the dye and the micelles. It was also observed that the aggregation of surfactant and dye takes place at a surfactant concentration below the CMC of the individual surfactant. The partition coefficients between the bulk water and surfactant micelles as well as the Gibbs energies of distribution of dye between the bulk water and surfactant micelles were calculated using a pseudo-phase model. The effect of the hydrophobic chain length of Gemini cationic surfactants on the distribution parameters was also reported. The results show favorable solubilization of dye in cationic micelles.

The solubilization and interaction of an azodye (methyl orange) with dodecyl trimethyl ammonium bromide and cationic gemini surfactants in the series of alkanediyl a,x-bis[(dimethyl alkyl ammonium)bromide)] referred to as (m-s-m), m = 10, 12, 14 and s = 2, 3, 4 were investigated by means of UV-Vis spectroscopy. Aggregation with the anionic dye was reflected by a hypsochromic shift with a decrease in the intensity of the absorption band. The results also show a bathochromic shift followed by a sharp increase in the intensity of the maximum absorption band k max after the critical micellar concentration (CMC). This indicates that the dye solubility increased with increasing surfactant concentration. It was also observed that the aggregation of surfactant and dye takes place at a surfactant concentration far below the CMC of the individual surfactant. The effects of the chain length as well as the spacer length of gemini surfactants on the critical aggregation concentration and CMC were also examined. Moreover, the partition coefficients between the bulk water and surfactant micelles K S and K X as well as the Gibbs energies of distribution of dye between the bulk water and surfactant micelles were determined using the pseudophase model. The effect of the hydrophobic chain length and spacer of gemini surfactants on the distribution parameters is also reported.
