Synthèse et étude du comportement en milieu aqueux de tensioactifs gémini glycosylés

Abstract

Dans ce travail nous décrivons la synthèse et l'étude des propriétés physico-chimiques de nouveaux composés gemini non ioniques glycosylés hydro-et perfluorocarbonés derivés du tris(hydroxymethyl)-aminomethane. La nature du bras espaceur et des chaînes latérales ont été modulées de manière à déterminer leur impact sur les propriétés d'organisation en milieu aqueux de ces nouveaux tensioactifs. La nature des agrégats qu'ils forment dans l'eau a été étudiée par MET après coloration négative. La longueur et la rigidité du bras écarteur semblent jouer un rôle prépondérant sur le type d'organisation formé par ces composés : système prémicellaire, micelles, vésicules ou agrégats divers.

Synthesis and study of the behavior of glycosylated gemini surfactants in aqueous media. The work reported herein deals with the synthesis and physico-chemical studies of a new kind of glycosylated non-ionic gemini surfactants. These compounds derive from tris(hydroxymethyl)aminomethane and bear hydro- or perfluorocarbon tails. The chemical structures of the spacer arm and hydrophobic tails were adjusted in order to specify their impact on the gemini surfactant behavior in aqueous media. The supramolecular systems they form were studied by TEM after negative staining. The length and the rigidity of the spacer arm seem to play a key role in the aggregation behavior of these surfactants in water. With the appropriate modifications, the formation of premicellar associations, micelles, vesicles or various aggregates can be observed.
