Designing Electrically Anisotropic Materials via Self-Assembly of Liquid Crystalline Components

威廉姆斯学院化学系的Lee Park教授在无机、生物无机和有机金属化学项目的支持下，对制备电各向异性材料的策略进行了材料化学研究。电各向异性材料将通过精心设计离散的小分子来制备，这些小分子可以通过非共价相互作用聚集在一起，形成一维结构。待探索的材料包括一系列供体-受体稳定的液晶化合物，Pt2+基金属生成材料，含金属液晶系统，以及使用化学修饰氧化铝模板的柱状材料的对准策略。金属合成原和待开发的单个组分分子可以作为超分子合成的基础。此外，这些材料具有作为新型八极性材料的NLO应用潜力。这项研究将侧重于通过合成以特定方式聚集的小分子来开发新材料，通过液晶相，产生具有各向异性特性的超分子结构。在该奖项下研究的金属生成材料，含金属液晶系统，是广泛材料科学应用的有吸引力的候选人，在分子尺度电子学中具有潜在的用途，包括传感器，或作为非线性光学材料。本科生将在材料合成和表征方面接受多方面的培训。

Professor Lee Park of Williams College Chemistry Department is supported by the Inorganic, Bioinorganic and Organometallic Chemistry program for her materials chemistry studies on strategies for preparing electrically anisotropic materials. Electrically anisotropic materials will be prepared via the careful design of discrete small molecules that can aggregate by means of non-covalent interactions to give a one-dimensional structure. Materials to be explored include a family of donor-acceptor stabilized liquid crystalline compounds, a Pt2+ based metallomesogenic materials, metal-containing liquid crystal systems, and alignment strategies for columnar materials using chemically modified alumina templates. Metallomesogens and the individual component molecules to be developed may serve as building blocks for supramolecular syntheses. Also, these materials have potential for NLO applications as novel octupolar materials. This research will focus on the development of new materials through the synthesis of small molecules that aggregate in a specified manner, via a liquid crystalline phase, to give rise to supramolecular structures with anisotropic properties. The metallomesogenic materials, metal-containing liquid crystal systems, studied under this award are attractive candidates for a wide range of materials science applications, with potential uses in molecular scale electronics, including sensors, or as nonlinear optical materials. Undergraduate students will receive multifaceted training in materials synthesis and characterization.
