Abstract:

Hydrogen bonds, with their moderately directional characteristics and predictable patterns, are especially useful instructions, and their incorporation in molecules has resulted in a spectacular array of assemblies:Molecular ribbons, tapes, sheets, cages, rosettes, cubes, and capsules have been designed, synthesized, and characterized, both in solution and in the solid state. For example, Wyler, de Mendoza and Rebek have extended the range of architectures that have been self-assembled by hydrogen bonds.
