Supramolecular Chemistry

Definition

Supramolecular chemistry is the study of non-covalent interactions that lead to the formation of complex structures from smaller units. This field focuses on how these interactions can be used to create organized systems that exhibit properties and functions beyond those of the individual components. It plays a crucial role in processes like self-assembly and the development of advanced materials, such as self-healing systems, which mimic natural processes for repair and regeneration.
