Responsive Cyclohexane‐Based Low‐Molecular‐Weight Hydrogelators with Modular Architecture

Abstract

pH-sensitive gels: By using a cyclohexane-based scaffold to which various amino acid based substituents can be connected, low-molecular-weight compounds were obtained that can gelate water at very low concentrations. Their modular design (see picture: AA=amino acid(s), X=hydrophilic substituent, dark purple=hydrophobic region, light purple=hydrophilic region), allows tuning of the thermally and pH-induced reversible gel-to-sol transition of their gels.
