Molecular gels are semi-solid like viscoelastic materials consists of low concentration of a gelator (low molecular mass compound) and a liquid. This presentation will summarize the self-assembly, structure and properties of molecular gels derived from N-phenyloctadecanamides and N-(phenylalkyl)octadecanamides as molecular gelators. The nature of the self-assembly and gelation properties including critical gelator concentrations, gel-sol transition temperatures, thermodynamic, and mechanical properties will be presented. Many of these derivatives gelate water (hydrogel) and many organic liquids (organogels) as well as exhibit thixotropic properties. These results show that simple structural modifications of N-phenyloctadecanamides and N-(phenylalkyl)octadecanamides derivatives can cause very large changes in the properties of their gels. We thank Prof. Richard Weiss (Georgetown University) for the use of rheometer and polarizing optical microscope.
