RESUMEN
A series of novel amphiphiles were synthesized based entirely on renewable resources. Besides their efficacy as supramolecular gelators in a wide variety of organic solvents and also water, their surface properties as surfactants and emulsifiers have been determined. A methodical study revealed that the length of the hydrocarbon chains has a dramatic and decisive influence on the thermal stabilities of the obtained hydrogels.

A library of novel, lipid-modified derivatives of ascorbic acid was shown to exhibit highly attractive properties as surfactants, emulsifiers, oil soluble antioxidants, and highly effective gelators in organic solvents and especially water. In these systems, intermolecular hydrogen bonding and van der Waals forces act synergistically to induce gelation as confirmed by spectroscopic studies. The morphology of the formed gel has been characterized by scanning electron microscopy.
