Synthesis of Monodisperse Perfluoroalkyl-Oxyethylene Surfactants with Methoxy Capping: Surfactants of High Chemical Inertness
Selve, Claude,Achilefu, Samuel
, p. 911 - 912 (2007/10/02)
Monodisperse fluoroalkyl non-ionic surfactants with a methoxy group capping the hydrophilic head, and having a high chemical inertness and surface properties typical of perfluorinated non-ionic surfactants, have been synthesized.
246. Monofunctional (Dimethylamino)silane as Silylating Agent

The reaction of triorganyl(dimethylamino)silanes with surface-hydrated silicon dioxide has been studied.These silylating agents are easy to prepare from the corresponding chloro or bromosilanes with dimethylamine.The resulting products are thermally stable and relatively volatile.Reaction with surface-hydrated silicon-dioxide preparations at a50-250 deg C for 170 h yields a dense grafted layer.However, with (dimethylamino)silanes having strongly polar substituents, a retreatment of the surface-modified silica seems to be necessary in order to attain maximum coverage.
Neutral Ligands with Surfactant-Type Structure - Synthesis, Complexation, and Ion Transfer
Weber, Edwin
, p. 770 - 801 (2007/10/02)
New lipophilic neutral ligands which combine crown ether and podand characteristics with structural features of surfactants (cf. formulas 1-12, 16-26) were synthesized.Their complexation behaviour was studied, their solid-to-liquid and liquid-to-liquid phase transfer properties as well as their efficiency in ion transport across a liquid model membrane.Crystalline stoichiometric complexes of the cycles 2a-4a and of 3e with NaSCN, Ba(SCN)2, and BaI2 can be isolated.Among the noncyclic representatives a crystalline complex is obtained only from 11 with BaI2.The ligand 8d behaves in aqueous solution as a typical surfactant showing micelle formation and cloud point.
