This research program is based around the preparation and study of molecules derived from arylacetylene scaffolding, namely dehydrobenzoannulenes (DBAs), tetrakis(arylethynyl)benzenes (TAEBs), and azaacenes, to answer fundamental scientific questions as well as to explore their materials properties. With the support of this award from the Chemical Synthesis Program of the Division of Chemistry at the National Science Foundation, Professor Michael Haley of the Department of Chemistry at the University of Oregon will explore the development of facile synthetic methods for the assembly of functional molecules comprised of benzene and acetylene building blocks. The study of such molecules answers fundamental questions regarding the electronic structure of organic (carbon-based) materials, and also presents opportunities for practical applications, particularly in the area of nanotechnology. This project serves as an excellent training ground for graduate and undergraduate researchers in fundamental and applied chemical synthesis. The studies will provide the researchers with broad experience in organic synthesis, computational chemistry, x-ray crystallography, and fundamental aspects of aromaticity, electron delocalization, and molecular architecture. The broader impacts of this program include industrial internships of graduate students at local and regional companies and national labs, the exchange of graduate students with those of foreign collaborators in Germany, Denmark, and Japan, the hosting of extended stays of visiting scientists including professors from PUIs, and continued substantial involvement of undergraduates in state-of-the-art chemical research via programs which promote the participation of underrepresented groups.

本研究项目以制备和研究源自芳基乙炔支架的分子为基础，即脱氢苯环烯（DBAs），四（芳基乙炔）苯（TAEBs）和氮杂环烯，以回答基本的科学问题并探索其材料特性。在美国国家科学基金会化学部化学合成项目的支持下，俄勒冈大学化学系的Michael Haley教授将探索由苯和乙炔组成的功能分子组装的简易合成方法的发展。对这些分子的研究回答了有关有机（碳基）材料电子结构的基本问题，也为实际应用提供了机会，特别是在纳米技术领域。该项目为基础和应用化学合成方面的研究生和本科生研究人员提供了一个极好的训练基地。这些研究将为研究人员提供在有机合成、计算化学、x射线晶体学以及芳香性、电子离域和分子结构等基础方面的广泛经验。该计划的广泛影响包括研究生在当地和地区公司和国家实验室的工业实习，研究生与德国，丹麦和日本的外国合作者的研究生交换，接待包括PUIs教授在内的访问科学家的长期停留，以及通过促进未被充分代表的群体参与的项目，本科生继续大量参与最先进的化学研究。
