A small nonpolar amphiphile , namely, the semifluorinated alkane C 8 F 17 C 16 H 33 , forms monodisperse surface micelles [ca. 300 Å in diameter; see AFM image (a)] in which the fluorinated segments point outwards and the hydrocarbon segments inwards. A disklike model (b) allows the micelle size to be predicted from the lengths of the fluorinated and hydrocarbon segments of such molecules.
