Abstract. Recently gemini surfactants have attracted considerable attention due to their diverse applications and novel molecular architecture differing with regard to polar head groups, the hydrocarbon chains and the type and. size of the spacers. The present paper reports conductometric, surface tension and fluorescence measurements of physicochemical properties of some novel gemini surfactants (alkanediyl-α,ω-bis (dimethylhexadecylammonium bromide) (C16-s-C16.  2Br, where s = 3, 4, 6) and its derivatives i.e. alkanediyl-α,ω--bis(hydroxyethyhmethythexadecylanunonmm bromide) (C16-s-C16.  MEA 2Br·, where s = 4, 6)) in aqueous solution at 300 K. The interfacial parameters and aggregation number have also been presented. Thermodynamic parameters viz. Gibb's free energy change for micellizarion  (AG0 m) and Gibbs free energies.of adsorption  (ads) bas been  evaluated. An attempt has been made to correlate physicochemical and self assembling properties with   their structure.

Keywords: Gemini Surfactant, Fluorescence, Micellar Properties, Thermodynamic Parameters, Surface Properties
