Boronate-Linked Polymeric Materials

获得这一奖项，有机和高分子化学计划支持南卡罗来纳大学的John Lavigne教授的研究，他将研究基于硼酸酯形成的自组装材料。这种共价但可逆的组装策略代表了设计新分子组装的新范例，提供了一种模块化和可预测的路线来生成网络和线性聚合物材料。该项目利用非水介质中的三角平面硼化合物和多营养的二刘易斯碱性化合物(即二元醇、二胺)，在构件之间形成硼酸键。这种方法与大多数关于硼酸/酯平衡的分子识别文献相反，后者侧重于两个分子单元的组装。通过改变构筑单元的形状、大小、价态和双Lewis碱性连接基，将合成一系列功能化的共价有机骨架(COF)以及其他新型的未取代骨架。将开展对这些新骨架的稳定性、结构、孔隙率以及气体吸收和储存的研究。此外，还将合成一系列线型聚硼酸酯S，并对其力学和电子性能进行研究。这些聚合物有望具有与传统共价聚合物和超分子聚合物类似的物理性能，将两者的优点结合在一起，创造出新的杂化材料。此外，还将研究功能性共轭聚(硼酸盐)S，以破译它们的性质和作为发光材料或可能的导电材料的潜在作用。获得该奖项后，有机和高分子化学计划支持南卡罗来纳大学的John Lavigne教授的研究，他的研究将制备硼酸盐连接的网络和线性聚合物，最终将导致创建新的纳米材料，用于分离、催化、存储、光学材料和传感领域的潜在应用。Lavigne博士和他的学生(包括研究生和本科生)将接触到广泛的主题，包括有机、材料、物理和超分子化学。学生将在高度多学科的环境中接受培训，成为更好的问题解决者，不仅是在微观层面，而且在更全球的层面上也是如此。此外，鉴于项目的多样性，学生需要与其他研究人员互动并进行小组工作，帮助他们培养沟通技能，并学习作为团队的一部分进行工作。这笔赠款的资助将允许学生继续追求他们的教育和专业目标，同时还支持主要面向非科学家受众的社区外联和课程开发。

With this award, the Organic and Macromolecular Chemistry Program supports Professor John Lavigne of the University of South Carolina whose research will study self-assembling materials based on boronate ester formation. This covalent yet reversible assembly strategy represents a novel paradigm in designing new molecular assemblies, providing a modular and predictable route to generate network and linear polymeric materials. The project utilizes trigonal planar boron compounds and polytrophic di-Lewis basic compounds (i.e. diols, diamines) in non-aqueous media, forming boronate linkages between building blocks. This approach is in contrast to the majority of molecular recognition literature on boronic acid/ester equilibria which focuses on the assembly of two molecular units. A series of functionalized covalent organic frameworks (COFs) will be synthesized as well as other novel unsubstituted frameworks by varying the shape, size, valency and di-Lewis basic linkers of the building blocks. Studies to probe the stability, structure, porosity and gas uptake and storage of these new frameworks will be carried out. Additionally, a series of linear poly (boronate)s will be synthesized and their mechanical and electronic properties investigated. These polymers are expected to have physical properties analogous to both traditional covalent polymers and supramolecular polymers, taking the best from both worlds to create new hybrid materials. Furthermore, functional conjugated poly (boronate)s will be studied to decipher their properties and potential roles as emissive or possibly conducting materials.With this award, the Organic and Macromolecular Chemistry Program supports Professor John Lavigne of the University of South Carolina whose research will prepare boronate linked networks and linear polymers that will ultimately lead to the creation of new nano-scale materials for potential applications in the areas of separations, catalysis, storage, optical materials, and sensing. Dr. Lavigne and his students (both graduate and undergraduate) will be exposed to a wide range of topics including organic, materials, physical, and supramolecular chemistry. Students will receive training in a highly multidisciplinary environment to become better problem solvers not just on the microscale, but also on a more global scale. Furthermore, given the diverse nature of the project, students will need to interact with other researchers and work in groups, helping them develop communication skills and learn to work as part of a team. Support from this grant will allow students to continue the pursuit of their educational and professional goals while also supporting the development of community outreach and curriculum development for primarily non-scientist audiences.
