What are Supramolecular Assemblies?
Supramolecular assemblies refer to complex structures formed through non-covalent interactions among various molecules. These interactions include hydrogen bonding, van der Waals forces, π-π interactions, and electrostatic forces. Unlike traditional covalent bonds, these forces are reversible, allowing for dynamic and adaptive structures that can respond to environmental changes.
How are Supramolecular Assemblies Relevant to Nanotechnology?
