大卫教授L.西华盛顿大学的帕特里克得到化学系分析和表面化学项目的支持，研究使用热致液晶溶剂制备具有受控分子和宏观尺度秩序的有机薄膜。 液晶溶剂将与单晶石墨衬底相结合，系统地和合理地打破分子单层中的构型对称性。 该技术提供了对分子取向、手性、多态性和构象的控制。 将开发的方法系列将共同扩展有机薄膜生长技术的现代工具包，允许制备具有新组织维度的薄膜。对有机薄膜中分子的排列施加结构控制的能力影响了不同学科中的广泛研究领域，其中需要在技术相关的基底上形成有序的膜。 直接受到影响的研究领域包括手性色谱、非线性光学材料、对映选择性传感器、液晶器件用偏振膜和催化剂。 本科生将在研究的各个方面接受培训和经验。

Professor David L. Patrick of Western Washington University is supported by the Analytical and Surface Chemistry Program in the Division of Chemistry to investigate the use of thermotropic liquid crystal solvents for preparing organic thin films with controlled molecular- and macroscopic-scale order. Liquid crystal solvents will be combined with single crystal graphite substrates to systematically and rationally break configurational symmetry in molecular monolayers. The technique affords control over molecular orientation, chirality, polymorphism, and conformation. Together the family of methods that will be developed will extend the modern toolkit of techniques for organic thin film growth, allowing the preparation of films engineered to possess new dimensions of organization. The ability to exert structural control over the arrangement of molecules in organic thin films impacts a wide range of research areas in different disciplines where there is a need for ordered films on technologically relevant substrates. Research areas that are directly impacted include chiral chromatography, nonlinear optical materials, enantioselective sensors, polarizing films for liquid crystal devices, and catalysts. Undergraduate students will receive training and experience in all aspects of the research.
