Molecular and Supramolecular Morphogenesis

The design of exoreceptors requires a means of generating defined external molecular shapes. This may be achieved by the stepwise synthesis of molecular architectures via covalent bond formation (covalent or molecular morphogenesis). The polymerization of oriented systems in molecular assemblies may also serve this end [7.10]. 

Another approach to controlled molecular morphogenesis is provided by the generation of globular molecules such as the starburst dendrimers and the arborols , based on highly branched structures formed via cascade processes and growing from a central core [7.55-7.60]. Most such molecular scaffolding hase been produced by repetitive processes the use of sequences of different reactions is expected to give access to an even richer variety of non-repetitive branched architectures. 

Molecular and supramolecular morphogenesis is at its highest expression in the generation of biological structure in the course of the development of living organisms [7.63].
