Cationic polyfluorinated surfactants (CnF2n+1CONH(CH2)(2)N+(CH3)(2)(CH2)(15)CH3Br-; CnF (n = 1-3)) form reversed micelles in organic solvents such as toluene. The reversed micelle formation and their properties were studied by H-1 NMR and F-19 NMR measurements. The cmc (critical reversed micelle concentration) and the aggregation numbers of reversed micelles formed by fluorinated surfactants were determined. The aggregation numbers of reversed micelles formed by fluorinated surfactant were calculated to be 9-12 in toluene. According to the analysis of NMR longitudinal relaxation time T-1, the polyfluorinated reversed micelles were shown to have a very unique microstructure, in which the perfluoroalkyl chains orientate at the interface between organic and water phase, and the mobility of perfluoroalkyl chains in reversed micelles was relatively larger than that of micelles and vesicles. The F-19-T-1 values of fluorine nuclei in the terminal trifluoromethyl group of were 750 +/- 23, 740 +/- 29, and 855 +/- 93 ms for C1F, C2F and C3F, respectively.
