A novel Na+ coordination mediated supramolecular organogel based on isosteviol: water-assisted self-assembly, in situ forming and selective gelation abilities

Abstract

A novel sodium sulfonate gelator self-assembles through water-assisted Na⁺ coordination to gelate halohydrocarbon solvents selectively with a C_gel as low as 0.1% w/v. In situ gel formation can be achieved by adding the relative sulfonic acid to an organic solvent–brine two-phase system at room temperature.
