With this award, the Organic and Macromolecular Chemistry Program supports the work of Professor Gideon A. Fraenkel of Ohio State University. This research will involve investigation of carbanions by studying the structure and behavior of selected organolithium compounds using a unique combination of synthesis, NMR spectroscopy, X-ray crystallography and quantum chemical calculations. The dynamics and mechanisms by which these compounds reorganize and interconvert at equilibrium, the latter using NMR line shape analysis, will be determined. These studies are designed to produce a new way to count lithium atoms in clusters of organolithium compounds in the amorphous phase, a better understanding of the extent of electron delocalization in conjugated anions and a new and unusual approach to making ladder polymers.The broader impacts of this research involve the training of young scientists, including undergraduates, women and those in underrepresented minorities in a broad variety of areas using a combination of techniques and skills. This will prepare these students for careers in industry or academia. Various industrial companies use the techniques which have been developed, for example synthetic applications in polymer chemistry and the NMR spectral technique to monitor reactions. There will continue to be a variety of collaborations with industrial companies, as well as with chemists at other universities.

有了这个奖项，有机和高分子化学计划支持吉迪恩教授的工作。俄亥俄州州立大学的Fraenkel。 这项研究将涉及碳负离子的调查，通过研究选定的有机锂化合物的结构和行为，使用合成，NMR光谱，X射线晶体学和量子化学计算的独特组合。 将确定这些化合物在平衡时重组和相互转化的动力学和机制，后者使用NMR线形分析。 这些研究旨在产生一种新的方法来计算无定形有机锂化合物簇中的锂原子，更好地理解共轭阴离子中电子离域的程度，以及一种新的和不寻常的方法来制造梯形聚合物。这项研究的更广泛影响涉及年轻科学家的培训，包括本科生，妇女和代表性不足的少数群体在广泛的领域使用技术和技能相结合。 这将为这些学生在工业或学术界的职业生涯做好准备。 各种工业公司使用已经开发的技术，例如聚合物化学中的合成应用和NMR光谱技术来监测反应。 将继续与工业公司以及其他大学的化学家进行各种合作。
