The surface modification of deep-cavity cavitands has been demonstrated by using the azide-alkyne “click” coupling to attach dendritic macromolecules or linear polymers onto their periphery. The resulting set of macromolecular cavitands exhibited tuneable solubility yet retained the ability to encapsulate guest molecules.
