Low Molecular Weight Gelators (LMWG) have been of great interest in the fields of medicine and public health. These compounds form gels, which are supramolecular polymers formed by the aggregation of gelator molecules through weak, reversible, non-covalent interactions such as hydrogen bonding, π-π stacking, and London dispersion forces. Previous research in our group has focused on the synthesis of a series of novel hydrazide- and oxadiazole-based LMWGs, which have demonstrated gel formation when 0.5 equivalent of a metal ion was added to &lt; 2% of the LMWG. The focus of this research was to characterize the thermal stability and the structural organization of the resulting metallogels using solution (NMR and IR) and solid-state (SEM and X-ray Diffraction) techniques. The evaluation of the thermal stability of these metallogels and the analysis of the resulting supramolecular structures will provide us with an understanding of the molecular components required for gel formation. Details of these studies will be discussed in this presentation.
