The research work of Jean-Marie Lehn led in 1968 to the synthesis of cage-like molecules that form inclusion complexes, the cryptates, with various metal ions. With this began his research on the chemical basis of ‘molecular recognition‘ , which also plays a fundamental role in biological processes. For these studies Lehn received the Nobel Prize for Chemistry in 1987.
Over the years, Lehn’s main line of research has expanded from the studies on molecular recognition to the definition and exploration of a new field of chemistry, which he proposed calling ‘supramolecular chemistry‘ as it deals with the complex entities formed by the association of two or more chemical species held together by intermolecular forces, whereas molecular chemistry studies the features of the entities constructed from atoms linked by covalent bonds. Using these strategy, he has built helicates, grids, cylindrical cages, and rotaxanes.
In the helicate work, Lehn has used molecular strands consisting of several bidentate binding sites, such as 2,2′-bipyridine, separated by spacers. When linear strands having, say, five bipyridine units are mixed with metal ions (such as Cu+) in solution, the strands wrap themselves around a row of five metal ions, forming double-helical metal complexes. Strands containing sequences of bidentate and tridentate binding sites, when exposed to two metal ions having different coordination geometries, will wrap around a row of metal ions having the most suitable coordination geometry for each binding site. Lehn’s group has used these principles to prepare a variety of double- and triple-helical complexes, including a complex in which two different strands form a double helix.
Supramolecular chemistry is intrinsically a dynamic chemistry in view of the lability of the non-covalent interactions connecting the molecular components of a supramolecular entity and the resulting ability of supramolecular species to exchange their components. The same holds for molecular chemistry when the molecular entity contains covalent bonds that may form and break reversibility, so as to allow a continuous modification in constitution by reorganization and exchange of building blocks. These features define a Constitutional Dynamic Chemistry (CDC) by Lehn on both the molecular and supramolecular levels.
Constitutional Dynamic Chemistry (CDC)
By combining the advantages of combinatorial chemistry and supramolecular chemistry, dynamic combinatorial chemistry may become a powerful tool for drug discovery and materials science.
