The self-assembly of molecular building blocks into ordered supramolecular structures enables the creation of nanomaterials that can display ligands on their surfaces with molecular precision. However, many of these supramolecular scaffolds face challenges in incorporating bulky or hydrophilic ligands, such as carbohydrates. This issue often requires the co-assembly of ligand-containing blocks with non-functionalized ones, diluting ligand presentation and compromising their precise spatial arrangement. Herein, we present carbohydrate oligomers that assemble into supramolecular nanomaterials featuring a molecularly controlled, dense presentation of carbohydrate ligands on their surfaces. This modular system accommodates a variety of carbohydrate ligands while maintaining consistent bulk material properties. Using this approach, we have engineered a series of supramolecular hydrogels, whose nanostructure displays specific carbohydrate residues with high density that act as biological cues to influence the morphology of Candida albicans.
