Macromolecular cages

In host–guest chemistry, macromolecular cages are a type of macromolecule structurally consisting of a three-dimensional chamber surrounded by a molecular framework. Macromolecular cages can be considered large-sized organic molecular cages. Macromolecular cage architectures come in various sizes ranging from 1-50 nm and have varying topologies as well as functions. They can be synthesized through covalent bonding or self-assembly through non-covalent interactions. Most macromolecular cages that are formed through self-assembly are sensitive to pH, temperature, and solvent polarity.
