This award in the Inorganic, Bioinorganic and Organometallic Chemistry program supports research by Professor Philip Power of the University of California at Davis to synthesize and characterize new main group compounds that are protected and stabilized by modified terphenyl ligands. This research investigates the fundamental characteristics of element-element bonding in compounds such as borylenes (univalent, monomeric organoboron(I) compounds), diborenes and dialuminenes with putative double bonds, and disilynes with silicon-silicon triple bonds. The structures, bonding and chemistry of the new compounds will be examined by multinuclear and dynamic NMR UV-Vis, IR, EPR and X-ray crystallography in order to correlate bonding and electronic changes that are difficult to describe in traditional terms of valency, orbital overlap, hybridization and bond order.This research will advance the fundamental understanding of the bonding of the main group elements including silicon, boron, aluminum and gallium. Graduate students, undergraduate students and postdoctoral associates will receive excellent training and research experiences in a forefront synthetic inorganic chemistry program.

无机，生物无机和有机化学计划的这一奖项支持加州大学戴维斯分校的Philip Power教授的研究，以合成和表征由改性三联苯配体保护和稳定的新主族化合物。 本研究调查元素元素键合的化合物，如borylenes（单价，单体有机硼（I）化合物），diborenes和dilaumenes与假定的双键，和disilynes与硅-硅三键的基本特征。 这些新化合物的结构、成键和化学性质将通过多核和动态NMR UV-Vis、IR、EPR和X-射线晶体学进行研究，以便将难以用传统的价态、轨道重叠、杂化和键级描述的成键和电子变化联系起来。这项研究将推进对主族元素包括硅、硼、铝和镓。研究生、本科生和博士后研究员将在前沿合成无机化学项目中获得出色的培训和研究经验。
