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
