Molecular Recognition

Lehn 1993: “Self-assembly of molecular and macromolecular systems is a versatile and modular tool for the creation of higher order structures” Nature employs self-assembly extensively using both phase segregation and “lock and key” specific interactions to generate the diverse range of highly ordered systems observed in living organisms. Applying biologically inspired self-assembly strategies to synthetic macromolecules provides access to a wide range of desirable structural and dynamic properties. Controlled non-covalent interactions are a particularly attractive strategy for controlling polymer aggregation, using the array of recognition elements developed by supramolecular chemists.
