The study of polymeric-sized supramolecules constructed by non-covalent self-assembly or self-organization ( Moore JS: Molecular architecture and supramolecular chemistry. Curr Opin Solid State Mater Sci 1996, 1:777-788) continues to be a growing activity leading to interesting materials with unique features. An evolving theme is the self-organization of large covalent objects (shape-controlled mesomolecules) having high-definition molecular surfaces. The folding of polymer molecules into conformationally ordered states is a new vista on the horizon.
