本研究旨在通过合成、表征和理论的共同努力，建立聚合物液晶(PLC)及其性质的基础科学。其方法是设计PLC行为的理论模型，利用计算机技术模拟其性质，制备模拟理论模型的化学体系，表征其结构和性质，将实验结果与理论相关联，迭代该过程以优化性质，使理论与实验相一致。可编程控制器作为电磁或光学存储器件以及高性能聚合物具有潜在的应用前景。要合成的聚合物被设计成两相的，侧基和聚合物主链独立运动。材料将通过核磁共振、X射线、介电和其他测量进行表征。将使用一种新的强磁场系统来定向样品以进行结构表征。

This research seeks to establish the fundamental science of polymer liquid crystals (PLCs) and their properties via a collaborative effort involving synthesis, characterization and theory. The approach is to devise theoretical models of PLC behavior, simulate their properties using computer techniques, prepare chemical systems emulating the theoretical models, characterize their structures and properties, correlate the experimental results with the theory and iterate the process to optimize properties and bring theory and experiment into agreement. The PLCs have potential applications as electromagnetic or optical storage devices, as well as high performance polymers. The polymers to be synthesized are designed to be biphasic, with independent motion of the side groups and the polymer backbone. The materials will be characterized by NMR, x-ray, dielectric and other measurements. A new high magnetic field system field system will be used to orient samples for structural characterization.
