Catanionic organogelators derived from D-sorbitol and natural fatty acids

Abstract

Several catanionic organogelators derived from 1,3:2,4-bis-O-(p- aminobenzylidene)-D-sorbitol (p-NH2-DBS) and hydroxy derivatives or natural fatty acids were synthesized, characterized and their gelation ability was evaluated. SEM observations of the xerogels formed by association of 1,3:2,4-bis-O(p-aminobenzylidene)-D-sorbitol and 12-hydroxystearic acid showed important modifications in the morphology and depend upon the nature of solvent as compared with the xerogels formed by each individual organogelator.
