A captivating challenge in chemistry lies in achieving robust and precise binding of uncharged, hydrophilic carbohydrate entities. Although past decades have provided a variety of excellent molecular architectures tailored for carbohydrate recognition, including acyclic receptors, macrocycles and foldamers, recent advances have highlighted the potential of synthetic molecular cages. These structures are equipped with intricately designed cavities that contain bespoke noncovalent binding sites for carbohydrate interactions. Constructed with the principles of complementarity and preorganization, these cage receptors demonstrate high affinity and exquisite selectivity in carbohydrate recognition through noncovalent interactions, capitalizing on multivalency and cooperativity. This Review highlights recent advances in the design and application of molecular cages with diverse structures, interactions and binding capacities for carbohydrate recognition. In the concluding remarks, we discuss future avenues for further exploration.
