This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).The Organic and Macromolecular Chemistry Program in the Chemistry Division at the National Science Foundation supports Professor Rajendra Rathore of Marquette University in a research project that will integrate the disciplines of synthetic organic chemistry, molecular recognition, and material science. The aim is to study and exploit new cofacially-stacked benzenoid structures that can be potentially utilized to develop various electronic and optoelectronic devices in the emerging field of nanotechnology. The study of the proposed novel molecules, using various spectroscopic techniques including time-resolved spectroscopy, will help to expand the understanding of through-space electronic coupling between cofacially arrayed phenylenes and eventually lead to functional materials for practical applications. The design and synthesis of new cofacially-stacked polyphenylene structures presents an important step that will lead to the development of a variety of new molecular and supramolecular nanostructures that will achieve photoinduced charge separation over long distances with high quantum efficiency and will create exciting challenges for future research.The broader impacts of the proposed research will present opportunities for high quality training for both graduate and undergraduate students in multidisciplinary research. Professor Rathore has shown a commitment to broadening participation by the inclusion of women and underrepresented groups in his group through active recruitment of these students. Marquette University has established close ties with Alcorn State University, a Historically Black University (HBCU), from which a number of graduate students have been recruited. By continuing to publsh his research in high quality journals, Professor Rathore will significantly impact the field of organic electronics.

该奖项是根据2009年美国复苏和再投资法案(公法111-5)资助的。国家科学基金会化学部的有机和高分子化学项目支持马凯特大学的Rajendra Rathore教授的一个研究项目，该项目将整合合成有机化学、分子识别和材料科学的学科。其目的是研究和开发新的表面堆叠的苯类结构，这些结构可以潜在地用于在新兴的纳米技术领域开发各种电子和光电子器件。利用包括时间分辨光谱在内的各种光谱技术对所提出的新型分子进行研究，将有助于扩大对共面排列的苯系物之间通过空间电子耦合的理解，并最终导致用于实际应用的功能材料。新的表面堆积聚苯结构的设计和合成是开发各种新的分子和超分子纳米结构的重要一步，这些纳米结构将实现长距离高量子效率的光致电荷分离，并将为未来的研究带来令人兴奋的挑战。拟议研究的更广泛的影响将为多学科研究的研究生和本科生提供高质量的培训机会。Rathore教授表示致力于扩大参与，通过积极招募这些学生，将妇女和代表性不足的群体纳入他的小组。马凯特大学与阿尔科恩州立大学建立了密切的联系，阿尔科恩州立大学是一所历史悠久的黑人大学(HBCU)，已经从该大学招收了一些研究生。通过继续在高质量的期刊上发表他的研究，Rathore教授将对有机电子领域产生重大影响。
