Design, Synthesis and Gelation of Low Molecular Weight Organo-Gelators Derived from Oleic Acid via Amidation

Abstract

In recent decades, gels have been widely considered for various medicinal purposes and, in particular, wound healing applications. In this regard, amides of oleic acids and 9, 10-dihydroxyoctadecanoic acid are synthesized and characterized with the help of modern analytical tools. Among the mentioned amide frameworks, N-(2-aminoethyl)-oleamide exhibits high order of gelation not only with different organic solvents such as n-hexane and DMSO but also with different edible oils such as sesame oil, mustard oil, coconut oil and citriodora oil. Here, we briefly discuss the optimization of gelation conditions for the synthesized amides as organo-gelator, in addition to that the minimum gelation concentration and gelation temperature have also been studied.
