项目摘要

This award in the Inorganic, Bioinorganic and Organometallic Chemistry program supports research by Professors Steven H Strauss and Olga V. Boltalina that focuses on the synthesis, isolation, and characterization of a new class of fluorochemical compounds based on fullerenes. Poly(perfluoroalkyl)fullerenes (PFAFs), are thermally (up to 600 C) and chemically stable and yield relatively stable radical anions, which may be isolated and studied as crystalline solids. Series of PFAFs, with varying chain lengths, compositions and structures will be prepared for the in 50-100+ mg quantities using the PIs' high-yield, high-temperature reactions of C60, C70, and other fullerenes with RfI reagents. Other synthetic methodologies will be explored, including substitution of halogen atoms in C60Xn and C70Xn derivatives. These latter reactions may produce kinetic isomers, which will allow the rates and mechanisms of intramolecular isomerization of a series of closely-related fullerene(X)n compounds to be studied in detail for the first time. Reaction conditions will be optimized for compositional and isomeric purity using a dynamic HPLC monitoring technique. The rigid cage structure of PFAFs, in which the Rf groups are attached to sp3 C atoms, will provide a unique opportunity to advance the understanding of through-space Fermi contact coupling between proximate F atoms in rigid sigma-bonded systems. The stability properties of PFAFs may allow them to be used for optoelectronic and nanoscale electronic devices, which would be explored in a separate collaborative project with NREL. The project involves collaborators in the US and abroad, with whom students will interact, which will broaden student education and help them build networks of professional colleagues.
无机,生物无机和有机化学计划的这一奖项支持Steven H Strauss教授和Olga V. Boltalina教授的研究,该研究侧重于基于富勒烯的一类新的含氟化合物的合成,分离和表征。 聚(全氟烷基)富勒烯(PFAF)是热稳定的(高达600 ℃)和化学稳定的,并且产生相对稳定的自由基阴离子,其可以作为结晶固体被分离和研究。将使用PI的高产率,C60,C70和其他富勒烯与RfI试剂的高温反应制备具有不同链长,组成和结构的PFAF系列,数量为50-100+ mg。 其他的合成方法将被探索,包括取代C60 Xn和C70 Xn衍生物中的卤素原子。 这些后者的反应可能会产生动力学异构体,这将允许一系列密切相关的富勒烯(X)n化合物的分子内异构化的速率和机制进行详细研究的第一次。将使用动态HPLC监测技术针对组成和异构体纯度优化反应条件。PFAF的刚性笼状结构,其中Rf基团连接到sp3 C原子,将提供一个独特的机会,以促进对刚性σ键合系统中邻近F原子之间的空间费米接触耦合的理解。PFAF的稳定性可以使它们用于光电和纳米级电子器件,这将在与NREL的单独合作项目中进行探索。该项目涉及美国和国外的合作者,学生将与他们互动,这将扩大学生教育,并帮助他们建立专业同事网络。
