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.

有了这个奖项，有机和高分子化学计划支持教授约翰拉维尼的南卡罗来纳州，其研究将研究基于硼酸酯形成自组装材料的大学。这种共价但可逆的组装策略代表了设计新分子组装体的新范式，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。该项目在非水介质中利用三角平面硼化合物和多元二路易斯碱性化合物（即二醇，二胺），在结构单元之间形成硼酸酯键。这种方法与大多数关于硼酸/酯平衡的分子识别文献相反，该文献侧重于两个分子单元的组装。通过改变结构单元的形状、大小、化合价和二-路易斯碱性连接基，可以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。将开展研究，以探索这些新框架的稳定性、结构、孔隙率以及气体吸收和储存。此外，我们还合成了一系列线型聚硼酸酯，并对其力学和电学性能进行了研究。这些聚合物预计具有类似于传统共价聚合物和超分子聚合物的物理性能，从两个世界中吸取最好的东西来创造新的杂化材料。此外，功能性共轭聚（硼酸盐）将被研究，以破译其性质和潜在的作用，作为发射或可能的导电材料。有了这个奖项，有机和大分子化学项目支持南卡罗来纳州大学的John Lavigne教授，他的研究将制备硼酸酯连接的网络和线性聚合物，最终导致新的纳米材料的产生。在分离、催化、存储、光学材料和传感领域的潜在应用的规模材料。Lavigne博士和他的学生（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。学生将在一个高度多学科的环境中接受培训，不仅在微观层面上，而且在全球范围内成为更好的问题解决者。此外，鉴于该项目的多样性，学生将需要与其他研究人员进行互动，并在小组中工作，帮助他们发展沟通技巧，并学会作为团队的一部分工作。这笔赠款的支持将使学生能够继续追求他们的教育和专业目标，同时也支持社区推广和课程开发的发展，主要是非科学家的观众。
