项目摘要

The United States is in need of more economical means to manufacture highly efficient lighting and displays. Methods that can rely upon inexpensive and abundant elements and ones that minimize the formation of wasteful and toxic byproducts are especially attractive. To meet this need the Synthesis Program of the Chemistry Division of the National Science Foundation supports the research of Professor John D. Protasiewicz of the Case Western Reserve University into the preparation of low cost/lightweight/processable plastics and materials related to light emitting technology. Examples, include polymers, molecular electronics, light emitting diodes, photovoltaics, and flexible electronics. The students and postdocs trained and educated as part of this research program are needed as part of the country's highly skilled workforce in industry and education. In addition to the technical broader impacts related to advanced manufaturing, Professor Protasiewicz co-organizes and runs special orientation programs directed at raising awareness of mental health issues among graduate students and faculty. Main group systems with novel reactivity and bonding modes are examined to advance and create new paradigms in photophysical chemistry. Building on recently developed multiply-bonded organophosphorus chemistry dynamic carbene chemistry, electropolymerization, and fluorescence turn-on chemosensors are explored. Isolable carbenes are examined as control elements in dynamic photochemical systems. Luminescent and functional derivatives of 1,3-benzoxaphopsholes (BOPs) and 1,3-benzazaphopsholes (BAPs) are examined to create P,O- and P,N-chelated complexes to serve as robust functional materials for light emitting diode applications. New routes to materials containing photoactive BOPs and BAPs are developed, as well as new types of electropolymerization reactions to produce materials with electrochromism. The Professor Protasiewicz co-organizes and runs special orientation programs directed at raising awareness of mental health issues among graduate students and faculty.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.

美国需要更经济的方法来制造高效的照明和显示器。那些可以依赖廉价和丰富的元素以及那些最大限度地减少浪费和有毒副产品形成的方法特别有吸引力。为了满足这一需要，美国国家科学基金会化学部的综合项目支持了约翰·D·史密斯教授的研究。Case Western Reserve University的Protasiewicz在低成本/轻质/可加工塑料和与发光技术相关的材料的制备中进行了研究。实例包括聚合物、分子电子器件、发光二极管、光致发光器件和柔性电子器件。作为该研究计划的一部分，学生和博士后接受培训和教育，是该国工业和教育领域高技能劳动力的一部分。除了与先进制造有关的技术更广泛的影响外，Protasiewicz教授还共同组织和运行专门的定向计划，旨在提高研究生和教师对心理健康问题的认识。研究具有新颖反应性和成键模式的主族体系，以推进和创造物理化学的新范式。基于最近发展的多键有机磷化学，探索了动态卡宾化学、电聚合和荧光开启化学传感器。研究了可分离卡宾在动态光化学体系中作为控制元素的作用。研究了1，3-苯并氧杂环戊二烯（BOP）和1，3-苯并氮杂环戊二烯（BAP）的发光和功能衍生物，以产生P，O-和P，N-螯合复合物，作为用于发光二极管应用的稳健功能材料。开发了含有光活性BOP和BAP的材料的新路线，以及新型的电聚合反应以产生具有电致变色的材料。Protasiewicz教授共同组织并开展了旨在提高研究生和教职员工对心理健康问题认识的特别定向项目。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智力价值和更广泛的影响审查标准进行评估来支持。
