Molecular Recognition Directed Self-Assembly of Supramolecular Polymers

Abstract

The first part of this paper discusses the molecular design of selected examples of structural units containing taper shaped exo-receptors and various crown ether, oligooxethylenic, and H-bonding based endo-receptors, which self-assemble into cylindrical channel-like architectures via principles resembling those of tobacco mosaic virus (TMV). The ability of these structural units to self-assemble via a delicate combination of exo- and endo-recognition processes will be presented. A comparison between various supramolecular (generated via H-bonding, ionic, and electrostatic interactions) and molecular 'polymer backbones' will be made. The present limitations concerning the ability to engineer the structural parameters of these supramolecular channel-like architectures and some possible novel material functions derived from them will be briefly mentioned. The second part of this paper will discuss our research on the molecular design of a novel class of macrocyclics which self-assemble via intramolecular recognition processes into supramolecular 'rod-like' collapsed macrocyclics which display thermotropic liquid crystalline mesophases
