Fundamental Properties and Applications of pi-Conjugated Platinum Carbene Chromophores and Polymers

有了这个奖项，化学系的大分子，超分子和纳米化学计划正在支持德克萨斯大学圣安东尼奥分校的Kirk尚泽教授。 这项调查汇集了几个不同的研究，探测分子暴露在光下时的基本激发态特性。 潜在的应用是基于有效的光发射（磷光），使材料作为有机发光二极管（OLED？特别是高效的深蓝色磷光体）、太阳能电池、光电探测器、传感器和用于医学诊断和治疗的材料，其在当今社会中被广泛使用。 这项研究将推进有关分子设计和合成的基本见解，这些分子有效地与商业，军事和卫生部门的大部分新技术的光贡献反应。 该奖项为本科生和研究生培训提供了新的机会。 教授尚泽开发教育和推广活动，涉及在科学技术工程数学（STEM）领域的代表性不足的群体在西班牙裔服务机构。 具体来说，他将开发和分发一个题为“为非科学家导航科学/技术文献”（NSTL）的模块，目的是教公众如何搜索和访问科学，技术，和专利文献，通过使用公共可访问的资源和/或通过使用传统的基于订阅的搜索和访问工具，通常可在当地大学。共轭有机配体为研究离域电子系统中自旋允许和自旋禁止电子激发态的基本性质提供了独特的机会。 这项研究的重点是几个不同的研究，探测基本激发态的性质和探索潜在的应用，特别是集中在新的铂卡宾基发色团和聚合物，表现出有效的光发射。 这种材料的发展扩大了可获得的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。 一个显著的潜在好处也可以通过开发一类新的高效深蓝色磷光体应用于OLED中而显现。 该项目推进了有机，有机金属和聚合物材料化学领域的知识，对有机电子的应用产生了潜在的影响。 特别强调的是扩大学生在这个项目工作的多样性。这个奖项反映了NSF的法定使命，并已被认为是值得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的支持。

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.
