(1) Being closely related to materials science, chemistry focuses on the atomic or molecular level, and materials science deals with macroscopic properties, however both together provide a proper understanding of how chemical composition, structure, and bonding of materials are related to the particular propertis.

(2) Molecular chemistry is concerned with uncovering and mastering the rules that govern the structure, properties, and transformations of molecular species, whereas the supramolecular chemistry is covering the structure and functions of organized entities of higher complexity formed by association of two or more chemical species held together by intermolecular forces.
