摘要：

Liquid-crystalline polymers have great potential as functional materials, in applications as varied as electrooptic devices or high-strength fibers. It is well-known that molecular interactions have a significant influence on the ordering of liquid-crystalline states. The proper combination of the shape of a molecule and the magnitude as well as the orientation of its interactions with neighboring species contributes to the liquid crystallinity of the molecule. In the case of some liquid-crystalline carbohydrates or poly(ester amides), intermolecular hydrogen bonds are present and contribute to the overall order of their mesophases. The objective of this study was to determine if a polymer containing a side-chain group capable of hydrogen bonding could be used to stabilize and enhance the mesomorphicity of a mesogenic small molecule with which it could interact through formation of hydrogen bonds.
