Liquid Crystal Synthesis

提出了各种各样的液晶材料的合成，需要测试理论概念，研究物理性质，并用于液晶显示器。从目前的NSF拨款中产生了新的想法，在一些领域需要额外的工作来完成正在进行的研究。因此，提出了以下具体问题的研究：设计用于显示的新手性材料（稳定胆甾，铁电和手性聚合物）并测试理论概念，继续进行分子修饰以寻找显示六相的B， F和I及其手性对应物的其他材料；用于相变研究的近晶a相以上大范围向列相材料的合成；用DMR制备氘化材料研究向列相的相分离继续合成新的聚合物材料，用于相变研究和聚合物分散液滴，并制备具有溶向性和热向列相的新材料，这些都具有理论和实践意义。这项工作将为液晶研究所乃至全世界的研究人员的物理研究提供已知的和新的液晶材料。它需要化学家和物理学家之间的广泛合作，因此将鼓励思想交流，并随着新信息的产生而修改研究目标。

The synthesis of a wide variety of liquid crystalline materials needed to test theoretical concepts, study physical properties, and for use in liquid crystal displays is proposed. New ideas have been generated by results from the current NSF grant, and in some areas additional work is needed to complete research in progress. Thus, investigation of the following specific problems is proposed: The design of new chiral materials for displays (stable cholesteric, ferroelectric, and chiral polymers) and to test theoretical concepts, continued molecular modifications to search for additional materials showing hexatic phases of smectics B, F, and I and their chiral counterparts; synthesis of materials with wide range nematic phases above a smectic A phase for phase transition studies; preparation of deuterated materials to study phase separation in nematic phases by DMR; continued synthesis of new polymeric materials for phase transition studies and for use in polymer dispersed droplets and preparation of new materials having lyotropic and thermotropic nematic phases which are of both theoretical and practical interest. This effort will provide both known and new liquid crystalline materials for physical studies by not only researchers at the Liquid Crystal Institute but throughout the world. It requires extensive cooperation between both chemists and physicists and will thus encourage the exchange of ideas and modifications in research goals as new information is produced.
