CRC: Next Generation Aromatics

乔治亚大学的格雷戈里·H·罗宾逊、罗伯特·B·金、亨利·F·谢弗、三世、保罗·冯·雷格·施莱耶和彼得·R·施莱纳得到了数学和物理科学局化学司和多学科活动办公室的支持，因为他们的跨学科合作旨在显著促进我们对芳香性和金属芳香性概念的理解。芳香族化合物的电子结构包含“移动电子的闭合回路”，从而提高了稳定性。它们的几何构型趋于规整，磁性和光谱性质都具有特殊的特征。为了研究下一代芳香族物种，这些研究人员将探索将芳香族M2(GAR)3化学扩展到其他元素的可能性。这些铅、锡、铊和铟的化合物，包括最初的目标Li2(InH)3，将从合成和理论两个角度进行研究。一个突出的目标将是合成一种真正的金属6 pi电子类似物--GA6-6部分。还将研究芳香性在超导电性、过渡金属衍生物、曲面(如Mobius芳烃)和新的环化反应中的作用。最后，本研究将探索评估分子物种芳香性的理论方法。化学合作研究奖(CRC)颁发给致力于广泛化学兴趣问题的科学家的跨学科团队。这些奖项的重点是研究和培训的新合作模式。

Gregory H. Robinson, Robert B. King, Henry F. Schaefer, III, Paul von Rague Schleyer and Peter R. Schreiner of The University of Georgia are supported by the Division of Chemistry and the Office of Multidisciplinary Activities of the Mathematical and Physical Sciences Directorate for their interdisciplinary collaboration aimed at significantly advancing our understanding of the concepts of aromaticity and metalloaromaticity. Aromatic compounds have electronic structures containing "closed circuits of mobile electrons" that lead to enhanced stabilities. Their geometries tend to be more regular and the magnetic as well as spectroscopic properties have special characteristics. To study next generation aromatic species, these researchers will explore the possibilities of extending the aromatic M2(GaR)3 chemistry to other elements. These compounds of lead, tin, thallium and indium, including the initial target, Li2(InH)3, will be studied from both synthetic, and theoretical perspectives. A prominent goal will be the synthesis of a truly metallic 6 pi-electron analog of benzene-a Ga6 6- moiety. The role of aromaticity in superconductivity, in transition metal derivatives, on curved surfaces such as Mobius aromatics and in new cyclization reactions will also be studied. Finally, this investigation will explore theoretical methods for evaluating aromaticity in molecular species. Collaborative Research in Chemistry (CRC) awards are given to interdisciplinary teams of scientists working on problems of broad chemical interest. The emphasis in these awards is on new collaborative modes of research and training.
