Abstract

Aqueous micellar solutions of cationic gemini surfactants belonging to 12-s-12 series (where s = 4, 5, 6) in presence of p-toluidine (PTD) exhibit a noticeable micellar growth/transition from viscometric and scattering studies. The dynamic light scattering (DLS) and small angle neutron scattering (SANS) showed pronounced micelle growth around pH 5–6 for gemini with varying spacer. The possible reason is attributed in terms of adsorption, surface charge density, chemical environment and orientation of PTD molecules in the micelle. The probable location of PTD in micelle is successfully correlated by the significant positive crosspeaks obtained from two-dimensional nuclear Overhauser effect spectroscopy (2D-NOESY).
