Supramolecular chemistry is a field of chemistry related to species of greater complexity than molecules,
that are held together and organized by means of intermolecular interactions.
The objects studied in supramolecular chemistry are supermolecules and other polymolecular entities that result from the spontaneous association
of a large number of components into a specific phase (membranes, vesicles,
micelles, solid state structures, etc).
