With the support of the Chemical Synthesis program of the Division of Chemistry, Professor Frieder Jäkle of the Department of Chemistry at Rutgers University-Newark will investigate conjugated materials that are functionalized with boron-nitrogen Lewis pairs. Conjugated materials are ones where electrons are delocalized easily over extended distances. They play major roles as in organic electronic devices and displays, photocatalysis, bioimaging, and therapeutics. By introducing boron into a conjugated material its electronic structure can be altered, which can result in desirable properties, for example, the absorption and emission of near-infrared light and are important characteristics for bio-imaging and biotherapeutic applications. This research addresses the need to develop new methods to prepare such compounds in order, in the longer term, to fully leverage their favorable properties in applications such as electronic materials development and catalysis, and for deployment in biomedical applications. In addition to the training of undergraduate and graduate students, high school outreach programs are planned that allow students and their teachers, including those from underrepresented groups, to experience University research first-hand, learn about modern research tools, while also being introduced to career opportunities in the science, technology, engineering, and mathematics (STEM) fields.The research project explores the functionalization of organic conjugated materials with boron-nitrogen (B-N) Lewis pairs as a means of tuning their electronic structure, photophysical properties, and chemical reactivity. In one direction, the research will target B-N Lewis pair-functionalized polycyclic aromatic hydrocarbons that feature reduced gaps between the highest occupied and lowest unoccupied molecular orbitals. Such systems are expected to absorb or emit in the near-infrared region and/or exhibit electrochromic properties. In another direction, heteroaromatic systems will be explored as potential chromophores for photoredox catalysis. Finally, macrocycles are being developed that combine luminescent, oxygen-responsive, and host-guest properties. The results are expected to offer new fundamental insights into the properties of organic materials that are functionalized with B-N Lewis pairs while also contributing to the development of luminescent, electrochromic, photocatalytic, host-guest, diagnostic and therapeutic materials.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.

在化学系化学合成项目的支持下，罗格斯大学纽瓦克分校化学系的Frieder Jäkle教授将研究用硼-氮刘易斯对官能化的共轭材料。共轭材料是电子在长距离上容易离域的材料。它们在有机电子器件和显示器、生物成像和治疗学中发挥着重要作用。通过将硼引入到共轭材料中，可以改变其电子结构，这可以产生期望的性质，例如近红外光的吸收和发射，并且是生物成像和生物荧光应用的重要特性。这项研究解决了开发新方法制备此类化合物的需求，以便从长远来看，充分利用其在电子材料开发和催化等应用中的有利特性，并用于生物医学应用。除了本科生和研究生的培训，高中外展计划，让学生和他们的老师，包括那些来自代表性不足的群体，体验大学研究的第一手资料，了解现代研究工具，同时也被介绍到科学，技术，工程，该研究项目探索了硼-氮（B-N）刘易斯对有机共轭材料的功能化，作为调整其电子结构，物理性质和化学反应性的手段。在一个方向上，研究将针对B-N刘易斯对官能化的多环芳烃，其特征是最高占据和最低未占据分子轨道之间的间隙减少。预期此类系统在近红外区域中吸收或发射和/或展现电致变色性质。在另一个方向，杂芳族系统将被探索作为潜在的生色团的光氧化还原催化。最后，正在开发的大环化合物具有联合收割机的发光、氧响应和主体-客体性质。该研究结果有望为B-N刘易斯对功能化的有机材料的性质提供新的基本见解，同时也有助于发光、电致变色、光催化、主客体、诊断和治疗材料的发展。该奖项反映了NSF的法定使命，并被认为值得通过使用基金会的知识价值和更广泛的影响审查标准进行评估来支持。
