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.

美国需要更经济的手段来制造高效的照明和展示。可以依靠廉价且丰富的元素以及最小化浪费和有毒副产品形成的方法特别有吸引力。为了满足这一需求，国家科学基金会化学部的合成计划支持西部储备大学的约翰·D·Protasiewicz教授的研究，以准备低成本/轻质/加工塑料以及与光发射技术相关的材料。例如，包括聚合物，分子电子，发光二极管，光伏和柔性电子设备。作为该国行业和教育方面高技能的劳动力的一部分，需要作为该研究计划的一部分进行培训和教育的学生和博士后。除了与先进的制造有关的技术广泛影响外，Protasiewicz教授共同组织并开展了旨在提高研究生和教职员工心理健康问题的特殊取向计划。检查了具有新颖反应性和键合模式的主要组系统，以推动和创建光物理化学的新范式。探索了最近开发的多键键入的有机磷化学动态碳纤维化学，电聚合剂和荧光转接化学传感器的基础。在动态光化学系统中，将隔离的卡宾人作为对照元件进行检查。检查了1,3-苯并ox孔（BOPS）和1,3-苯并paphopshopsholes（BAPS）的发光和功能衍生物，以创建P，O-和P，N链式复合物，以作为发光二极管应用的鲁棒功能材料。开发了含有光活性BOP和BAP的材料的新途径，以及新型的电聚合反应，以产生具有电色素的材料。 Protasiewicz教授共同组织并运行了特殊的取向计划，旨在提高研究生和教职员工的心理健康问题的认识。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子优点和更广泛的影响审查标准通过评估来进行评估的。
