- Abstract
A family of alkoxybenzoate derivatives was synthesized and were found to selectivity congeal protic/aprotic polar solvents, gasoline, and oils over water; therefore, these organogelators could be used in water remediation as removal agents of fuels and oils. Due to their thermoreversibility, they can be easily separated from the mixtures and be reused; being good candidates for fuel recovery. The π-π stacking interactions were evaluated to establish a relationship between their chemical structure and the gelation process through UV–vis spectroscopy; the three-dimensional network was studied with polarized optical microscopy (POM) and scanning electron microscopy (SEM). It was found that the aromatic ring acts as a stacking unit due to the π-π interactions; the ester group provides a source of dipole–dipole interactions; and the alkyl chains in the ether group showed a significant influence in gelation with the increase of carbon atoms, which increases the effect of nonpolar dispersion interactions.
