项目摘要

With this award, the Macromolecular, Supramolecular and Nanochemistry Program in the Division of Chemistry is supporting Professor Kirk Schanze at the University of Texas at San Antonio. This investigation brings together several distinct studies that probe the fundamental, excited state properties of molecules when exposed to light. Potential applications are based on efficient light emission (phosphorescence) which enables the materials to serve as organic light-emitting diodes (OLEDs ? particularly efficient deep blue phosphors), solar cells, photodetectors, sensor and materials for medical diagnostics and therapy, which are widely used in today's society. This research will advance fundamental insights with respect to the design and synthesis of molecules that efficiently react with light contribution to large sectors of new technologies in the commercial, military and health sectors. This award provides new opportunities for undergraduate and graduate student training. Professor Schanze develops education and outreach activities involving underrepresented groups in the science-technology-engineering-math (STEM) fields at a Hispanic Serving Institution. Specifically, he will develop and distribute a module entitled 'Navigating Scientific/Technical Literature for Non-Scientists' (NSTL) with the goal of teaching the general public how to search and access the scientific, technical, and patent literature by using publicly-accessible resources and/or by using traditional subscription-based search and access tools typically available at local Universities.Platinum acetylide molecules and polymers that contain pi-conjugated organic ligands provide a unique opportunity to investigate fundamental properties of spin-allowed and -forbidden electronic excited states in delocalized electronic systems. This research focuses on several distinct studies that probe fundamental excited state properties and explore potential applications, focused particularly on new platinum-carbene based chromophores and polymers that exhibit efficient light emission. Development of such materials expands the range of accessible optoelectronic organometallic materials and improves the understanding of relationships between chromophore structure and excited state properties. A significant potential benefit could also emerge by the development of a new class of efficient deep blue phosphors for application in OLEDs. The project advances knowledge in the fields of organic, organometallic and polymer materials chemistry with potential impacts on applications of organic electronics. Special emphasis is placed on broadening the diversity of students working on this project.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.

凭借该奖项，化学系的高分子、超分子和纳米化学项目正在支持德克萨斯大学圣安东尼奥分校的 Kirk Schanze 教授。这项研究汇集了几项不同的研究，这些研究探讨了分子暴露在光下时的基本激发态特性。潜在的应用基于高效的光发射（磷光），这使得该材料能够用作有机发光二极管（OLED？特别高效的深蓝色磷光体）、太阳能电池、光电探测器、传感器以及用于医疗诊断和治疗的材料，这些材料被广泛应用运用于当今社会。这项研究将推进有关分子设计和合成的基本见解，这些分子可与光进行有效反应，为商业、军事和卫生领域的大量新技术做出贡献。该奖项为本科生和研究生的培养提供了新的机会。 Schanze 教授在西班牙裔服务机构开展教育和外展活动，涉及科学技术工程数学 (STEM) 领域中代表性不足的群体。具体来说，他将开发和分发一个名为“非科学家导航科学/技术文献”(NSTL) 的模块，其目标是教导公众如何使用可公开访问的方式搜索和访问科学、技术和专利文献。资源和/或使用当地大学通常提供的传统订阅搜索和访问工具。含有 pi 共轭有机配体的乙炔铂分子和聚合物提供了独特的机会来研究自旋允许和-离域电子系统中禁止的电子激发态。这项研究重点关注几项不同的研究，探索基本的激发态特性并探索潜在的应用，特别关注具有高效发光能力的新型铂卡宾基发色团和聚合物。此类材料的开发扩大了光电有机金属材料的范围，并提高了对发色团结构和激发态性质之间关系的理解。开发用于 OLED 的新型高效深蓝色荧光粉也可能带来显着的潜在效益。该项目推进有机、有机金属和聚合物材料化学领域的知识，对有机电子学的应用产生潜在影响。特别强调扩大从事该项目的学生的多样性。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进行评估，被认为值得支持。
