摘要: Morpholinium-based amide-functionalized ionic liquids (ILs) [CnAMorph][Br], where n = 8, 12, and 16, have been synthesized characterized for their micellization behavior in aqueous medium using a variety of state the art techniques. The adsorption [CnAMorph][Br] ILs at air–solution interface bulk, respectively, has found to be much better compared that observed nonfunctionalized homologous conventional cationic surfactants, as shown by comparatively higher efficiency, lower surface tension critical micelle concentraiton (γcmc), concentration (cmc) ILs. Conductivity measurements performed obtain cmc, degree counterion binding (β), standard free energy (ΔGm°). Isothermal titration calorimetry provided information specifically about thermodynamics micellization, whereas steady-state fluorescence used ob...
