Abstract
Herein, we demonstrate how Cl, Br, and I substitutions influence supramolecular hydrogelation in glycosylated <i>N</i>-methylhalogenomaleimide amphiphiles. Bromine provides favourable intermolecular cohesion, yielding efficient and thermally robust hydrogels. Single-crystal X-ray analysis suggests cooperative hydrogen-bonding networks along with short Br⋯Br contacts, indicating that halogen bonds may serve as a tunable design element for functional soft materials.
