Supramolecular polymer science has matured into a technology ready for industrial application. This review begins with an overview of the principles underlying self-assembly of supramolecular polymers. Polymers developed over the past decade are discussed, with emphasis placed on stable hydrogen bonded structures that exhibit useful material properties. The commercial potential of such supramolecular polymers is also considered. (C) 2005 Springer Science + Business Media, Inc.
