Abstract

Vector-directional polymers and polymer systems are disclosed. In accordance with the embodiments of the invention, the polymer has aromatic moieties that are restrained or fixed through conformational linkage units bonding nearest neighbor aromatic moieties together to form the polymer backbone. The conformational linkage units preferably include conformational ring structures which exhibit hydrogen bonding or other Lewis acid-Lewis base type of interactions. The conformational ring structures can include hetero-atoms and cationic metal atoms. The chemical groups and bonding features of the polymer backbone constrain bond movement and bond rotation along the polymer backbone. Accordingly, the vector-directional polymers of the present invention can assemble into or form extended three dimensional structures or arrays.
