We report the properties of molecular gels based N-phenyloctadecanamide and N-(4-halophenyl)octadecanamides (X = F, Cl, Br and I) as low molecular mass gelators. Structure and properties of the molecular gels have been investigated using thermal, spectroscopic and rheological techniques. Comparison and correlation of the molecular structures of these gelators and the properties of their gels using critical gelator concentrations and gel melting temperatures will be presented. Some of the molecular gels have been found to be thixotropic and recover a large part of their viscoelasticity being destroyed by excessive strain shearing.
