Supramolecular Assemblies: A New Paradigm in Polymer Science

Supramolecular assemblies are formed through non-covalent interactions, such as hydrogen bonding, ionic interactions, van der Waals forces, and π-π stacking, between individual molecular components. These interactions, while weaker than covalent bonds, collectively give rise to highly organized structures with unique properties that are distinct from their individual constituents. Supramolecular polymer networks and gels are prominent examples of such assemblies, where polymer chains are interconnected via supramolecular interactions to form intricate three-dimensional architectures.
