Stimuli-responsive supramolecular hydrogels are a newly emerging class of aqueous soft materials developed based on modular molecular design. Glucosamine-based derivatives were found to be the only molecules capable of forming hydrogels, compared to galactosamine-based molecules.
Stimuli-responsive supramolecular hydrogels are a newly emerging class of aqueous soft materials with a wide variety of bioapplications. Here we report a reduction-responsive supramolecular hydrogel constructed from a markedly simple low-molecular-weight hydrogelator, which is developed on the basis of modular molecular design containing a hydrophilic amino sugar and a reduction-responsive nitrophenyl group. The hydrogel formation ability differs significantly between glucosamine- and galactosamine-based self-assembling molecules, which are epimers at the C4 position, and only the glucosamine-based derivative can act as a hydrogelator.
