“…Supramolecular gels from low molecular weight gelators (LMWGs) [1][2][3] are a class of soft functional materials with versatile properties that have recently garnered significant scientific interest for numerous applications including water purification [4,5], drug delivery [6], sensing [7,8], 3D printing [9], tissue engineering [10], as well as many others [11,12]. The hierarchical self-assembly of LMWG molecules results in anisotropic structures, most commonly fibers, which form physical networks capable of immobilizing the solvent by surface tension and capillary forces [13].…”

Mono-N-alkylated primary oxalamide derivatives with different sized branched alkyl tail-groups were excellent low molecular weight gelators for a variety of different organic solvents with different polarities and hydrogen-bonding abilities. Solvent-gelator interactions were analyzed using Hansen solubility parameters, while 1H NMR and FTIR spectroscopy were used to probe the driving forces for the supramolecular gelation. The molecular structures of the twin tail-groups did not significantly affect the supramolecular gelation behavior in different solvents. However, for select solvents, the molecular structures of the tail-groups did have a significant effect on gel properties such as the critical gelator concentration, thermal stability, gel stiffness, gel strength, network morphology, and molecular packing. Finally, metabolic activity studies showed that the primary alkyl oxalamide gelators had no effect on the metabolic activity of mouse immune cells, which suggests that the compounds are not cytotoxic and are suitable for use in biomedical applications.
