Abstract The formation of fibrous assemblies by fluorinated amphiphiles and the temperature-dependent fibril-vesicle transition were investigated by using microscopy and small-angle scattering. The results were compared with that of fibrous assemblies by nonfluorinated amphiphiles. Sodium (F-octylethyl) nonylmethyleneO-6-phosphoglucoside (F-Glu) formed hollow tubules in water at room temperature (∼25 °C). Tubules transformed into vesicles above 60 °C. Similar tubule-vesicle transition for hydrogenated-analog, sodium decylnonylmethyleneO-6-phosphoglucoside (H-Glu), was observed below room temperature. The mixture of [2-(F-octyl)penthyl] dimorpholinophosphate (F8C5DMP) and [2-(F-decyl)ethyl] dimorpholinophosphate (F10C2DMP) in water constructed U- or V- shape assemblies, which changed to vesicles at 60°C.
