Cover Picture: Generation of Dynamic Constitutional Diversity and Driven Evolution in Helical Molecular Strands under Lewis Acid Catalyzed Component Exchange (Angew. Chem. Int. Ed. 37/2004)

43_37/2004Helices and grids two most fascinating architectures, which have been the subject of intense recent studies in view of their significance in chemistry, biology, and material science, are represented in the cover picture. They are interconnected in a thermodynamic equilibrium generated by a Lewis acid catalyzed pathway involving a constitutional dynamic reorganization, self-assembly, and control of helical folding. For further details see the Communication by J.-M. Lehn et al. on page 4902 ff.
