CAREER: Buckybowls: A Controlled Switch of Metal Coordination

这项由无机、生物无机和有机金属化学项目颁发的职业奖支持了纽约州立大学奥尔巴尼分校Marina a . Petrukhina教授的研究工作，该研究旨在探索一类新型碳氢化合物的反应性和配位极限，即开放式测地聚烯烃（buckybowls），其内部和外部碳表面表现出不同的性质。本项目将采用一种新颖有效的气相沉积方法来控制巴基碗的配位性质，并揭示弯曲多芳烃在金属结合反应中的反应性的新方面。这些研究将探索基本的金属-对芳烃相互作用，重点是金属配位对非平面富碳芳烃表面的结构和反应性的扰动。对这类聚芳烃的系统研究是一个新的研究领域，它将刺激弯曲的富碳分子在材料合成中的应用。它将为不饱和碳表面的功能化以及富勒烯和纳米管的内切配合物的可控制备开辟新的实用途径，这些都是各种实际应用中非常理想的目标。与研究活动相结合的是一个培训和教育年轻化学家的项目，他们将把合成、晶体生长、各种表征技术、粉末和单晶衍射方面的专业知识与当前材料化学需求和挑战的知识和理解结合起来。这个教育项目将显著提高学生的专业发展，为他们成功的研究和教育事业做准备。它还应有助于化学系加强对材料化学的重视，增加科学专业的人数，并为学生在奥尔巴尼大学提供更好的学习环境。

This CAREER award by the Inorganic, Bioinorganic and Organometallic Chemistry Program supports work by Professor Marina A. Petrukhina at the University at Albany, SUNY, to explore the reactivity and coordination limits of a new class of hydrocarbons, namely open geodesic polyarenes (buckybowls), in which inside and outside carbon surfaces exhibit different properties. An original and effective gas phase deposition approach will be used in this program to control the coordination properties of buckybowls and to unravel novel aspects of the reactivity of curved polyaromatic hydrocarbons in metal binding reactions. These investigations will explore fundamental metal-p-arene interactions with an emphasis on the perturbation of structure and reactivity induced by metal coordination to non-planar carbon-rich aromatic surfaces. Systematic investigation of such polyarenes is a new area of research that should stimulate the use of curved carbon-rich molecules in materials synthesis. It should open new practical pathways for functionalization of unsaturated carbon surfaces and for controlled preparation of endo-complexes of fullerenes and nanotubes that are very desirable targets for a variety of practical applications. Coupled with the research activities will be a program created for training and educating young chemists who will combine expertise in syntheses, crystal growth, various characterization techniques, powder and single crystal diffraction with knowledge and understanding of current materials chemistry needs and challenges. This educational program should significantly enhance professional development of our students in preparation for their successful research and educational careers. It should also contribute to the efforts of the Department of Chemistry to strengthen the materials chemistry emphasis, to increase the numbers of science majors and to provide students with a better learning environment at the University at Albany.
