Highly fluorinated molecular organised systems: strategy and concept

Aggregation of new bipolar glucosyled and cationic fluoroamphiphiles in aqueous media

“…DLS results evidenced various kinds and structures of aggregates such as micelles for F7-Glu-NI, micelles and vesicles for F9-Glu-NI, and exclusively vesicles for F9-Glu-NI. The presence of vesicular or lamellar structures without the addition of co-lipids agreed with literature data for fluorocarbon or perfluorinated surfactants [1][2][3][4][5][6][7].…”

“…Thus, their ability to self-associate in water increases, giving low critical micelle concentrations (CMCs). Bilayer aggregates, stable vesicles, or other supramolecular structures are also possible without the addition of co-lipids, depending of the specific chemical structure of the fluorinated surfactant [1][2][3][4][5][6][7].…”

Studies on the effects of the alkyl group on the surface segregation of poly(n-alkyl methacrylate) end-capped 2-perfluorooctylethyl methacrylate films

“…Many polymers have been utilized in the preparation of partially fluorinated polymers [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22], such as poly(ethylene oxide), poly(acrylates/methacrylate)s, polysiloxanes, polyurethanes, and their random, block, and graft copolymers. From the viewpoint of both cost-saving and good water/oil repellency, it is desirable that most of the fluorinated groups can be segregated to the coating surface.…”

Cationic–anionic vesicle templating from fluorocarbon/fluorocarbon and hydrocarbon/fluorocarbon surfactants

“…In catanionic surfactant systems, this potential effect is offset by favorable electrostatic interactions of the head groups in catanionic surfactant systems [1,6]. The reduced permeability and increased stability of vesicle bilayers with the incorporation of fluorinated chains highlights the hydrophobic and lipophobic nature of the fluorinated chain [41]. For example, dimyristoylphosphatidylcholine (DMPC) liposome bilayers with incorporated perfluoroalkyl chains exhibited significantly less permeability to a hydrophilic fluorescent marker, carboxyfluorescein, encapsulated in the aqueous core of the liposomes [39].…”
