With the support of the Macromolecular, Supramolecular and Nanochemistry (MSN) Program in the Division of Chemistry, Professor Frieder Jäkle of the Department of Chemistry at Rutgers University-Newark will pursue boron-containing polymers as building blocks for new supramolecular materials. The electron-deficient character of boron compounds allows them to reversibly interact with electron-rich compounds such as amines or phosphines through so-called dative bonding. The reversibility of this dative bonding is appealing for developing ‘smart’ materials because the bond formation can be controlled through changes in temperature, concentration, and other stimuli. The Jäkle group aims to exploit this behavior to generate recyclable polymeric materials, including light-emitting materials that could find use in display technologies, bioimaging, and as sensors. The project will contribute to the training of a diverse body of undergraduate and graduate students in a highly interdisciplinary field of research. Planned materials chemistry outreach programs will allow students from local minority-serving high schools to experience University research and learn about career opportunities in the science and technology fields, while summer internships will provide hands-on research experiences. Polymer analysis capabilities will support the training of undergraduate students in teaching laboratories and enable research at nearby universities.Under this award, the Jäkle group will explore the synthesis and properties of polymers that are decorated with borane Lewis acids and Lewis acid-base pairs as means to add functionality and enable new applications. In one direction, the research targets polymeric Lewis pairs with interesting photophysical, electronic, and stimuli-responsive characteristics by ‘click’-like attachment of Lewis basic pi-conjugated chromophores to polymeric Lewis acids. Chromophores that contain multiple Lewis base groups are expected to lead to supramolecular polymer networks (SPNs) that feature photo-active dynamic crosslinks. Polymers that combine sterically hindered borane Lewis acid and Lewis base groups, so-called ‘frustrated’ Lewis pairs, will be studied in the activation of small molecules. In addition, collaborative efforts with other research groups at Rutgers, The State University and Boston College will be leveraged with the goal of generating fundamentally new classes of boron-containing polymers and hybrid nanomaterials.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

在化学系高分子、超分子和纳米化学 (MSN) 项目的支持下，罗格斯大学纽瓦克分校化学系的 Frieder Jäkle 教授将研究含硼聚合物作为新型超分子材料的构建模块。硼化合物的缺陷特征使其能够通过所谓的与格与富电子化合物（例如胺或膦）可逆地相互作用这种配位键的可逆性对于开发“智能”材料很有吸引力，因为可以通过温度、浓度和其他刺激的变化来控制键的形成，Jäkle 小组的目标是利用这种行为来生产可回收的聚合物材料，包括光。 - 发射材料可用于显示技术、生物成像和传感器，该项目将有助于在高度跨学科的研究领域培养多样化的本科生和研究生。当地少数族裔高中可以体验大学研究并了解科学技术领域的职业机会，而暑期实习将提供实践研究经验，聚合物分析能力将支持本科生在教学实验室的培训并促进研究。在该奖项的资助下，Jäkle 团队将探索用硼烷路易斯酸和路易斯酸碱对修饰的聚合物的合成和性能，作为增加功能和实现新应用的手段。在一个方向上，该研究的目标是聚合路易斯。与有趣的光物理、电子、通过路易斯碱性π共轭发色团与聚合路易斯酸的“点击”式连接，包含多个路易斯碱基团的发色团有望产生具有光活性动态交联的超分子聚合物网络（SPN）。将空间位阻硼烷路易斯酸和路易斯碱基团（所谓的“受阻”路易斯对）结合在一起的聚合物将在小分子的活化中进行研究。此外，还将进行合作研究。与罗格斯大学、州立大学和波士顿学院的其他研究小组一起，我们将致力于产生全新类别的含硼聚合物和混合纳米材料。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准。
