Supramolecular chemistry is the field of chemistry beyond that of molecules that focuses on chemical systems consisting of discrete numbers of subunits or assembled molecular components. The forces responsible for spatial organization can vary from weak (intermolecular forces, electrostatic or hydrogen bonds) to strong (covalent bonding), provided that the degree of electronic coupling between the molecular component remains low relative to the relevant energy parameters of the component . [8][9] While traditional chemistry focuses on covalent bonding, supramolecular chemistry examines weaker, reversible noncovalent interactions between molecules.[10] These forces include hydrogen bonding, metal coordination, hydrophobic forces, van der Waals forces, pi-pi interactions, and electrostatic effects.[11] Important concepts demonstrated by supramolecular chemistry include molecular self-assembly, folding, molecular recognition, host-guest chemistry, mechanically interlocked molecular architectures, and dynamic covalent chemistry.[12] The study of noncovalent interactions is crucial to understanding many biological processes, from cellular structure to vision, that depend on these forces for structure and function. Biological systems are often a source of inspiration for supramolecular research.
Supermolecules are to molecules and intermolecular bonding what molecules are to atoms and covalent bonding.
