项目摘要
With this award, the Chemical Structure, Dynamics & Mechanism Program is supporting Professor Anna Gudmundsdottir at the University of Cincinnati to investigate the solid-state photochemistry and photophysics of naphthoquinones and vinyl azides, using a combination of laser flash photolysis and x-ray crystallography. The goal of this research is to elucidate solid-state reaction mechanisms and to explain how a crystal lattice structure can affect reactivity. Professor Gudmundsdottir will integrate the research components of this project with an educational program designed to attract both high school and undergraduate students, with a focus on enhancing participation of students from groups that are underrepresented in science. Students will be provided with an opportunity to participate in research and educational activities that focus on professional development. The proposed research and the developmental teaching will lead to enhanced infrastructure within the Chemistry Department at the University of Cincinnati and serve as an outreach program for other schools in the region. This research will investigate the solid-state photoreactivity of naphthoquinones and vinyl azides by identifying their photoproducts and acquiring their X-ray structures. Laser flash photolysis will be used to characterize the transient excited states and radicals which are formed in the crystals and to determine the kinetics for their formation and decay. Collectively, these data will make it possible to elucidate detailed solid-state reaction mechanisms and to explain how the crystal lattice affects behavior of transient species and selection of the reaction products. Mechanistic studies will be supported by theoretical calculations. The planed studies, will lead to new knowledge in the field of photochemistry, reactive intermediates and solid-state chemistry. The proposed research will also contribute toward the design of crystal lattices for selective carbon-carbon and carbon-nitrogen bond formation from radicals, with a goal of using crystals as a matrix for solvent-free synthesis. Simultaneously, this research will contribute to the design of photoresponsive devices, such as solar cells and light emitting diodes.
有了这个奖项,化学结构,动力学机制计划正在支持辛辛那提大学的安娜Gudmundsdottir教授研究萘醌和乙烯基叠氮化物的固态光化学和光物理,使用激光闪光光解和X射线晶体学的组合。这项研究的目的是阐明固态反应机制,并解释晶格结构如何影响反应性。Gudmundsdottir教授将把这个项目的研究部分与一个旨在吸引高中和本科学生的教育计划相结合,重点是提高科学代表性不足的群体的学生的参与。学生将有机会参加以专业发展为重点的研究和教育活动。拟议的研究和发展性教学将导致辛辛那提大学化学系内的基础设施得到加强,并作为该地区其他学校的推广计划。 本研究将透过鉴定萘醌类及乙烯基叠氮化合物的光反应产物及获得其X光结构,来探讨其固态光反应性。激光闪光光解将用于表征晶体中形成的瞬态激发态和自由基,并确定其形成和衰减的动力学。总的来说,这些数据将有可能阐明详细的固态反应机制,并解释晶格如何影响瞬态物种的行为和反应产物的选择。机理研究将得到理论计算的支持。计划的研究,将导致在光化学,反应中间体和固态化学领域的新知识。拟议的研究还将有助于晶格的设计,以从自由基中选择性地形成碳-碳和碳-氮键,目标是使用晶体作为无溶剂合成的基质。同时,本研究将有助于光响应器件的设计,如太阳能电池和发光二极管。
