CRC: Next Generation Aromatics

格雷戈里·H罗宾逊，罗伯特B. King，亨利F. Schaefer，III，Paul von Rague Schleyer和Peter R.格鲁吉亚大学的Schreiner得到了化学系和数学与物理科学理事会多学科活动办公室的支持，他们的跨学科合作旨在显着推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“移动的电子的闭合电路”，这导致稳定性增强。 它们的几何形状趋于规则，磁性和光谱性质具有特殊的特征。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，包括初始目标，Li 2（InH）3，将从合成和理论的角度进行研究。一个突出的目标将是合成一个真正的金属6 π-电子类似物的苯-镓6 6-部分。芳香性在超导电性，过渡金属衍生物，曲面上的作用，如莫比乌斯芳烃和新的环化反应也将进行研究。最后，本研究将探讨评估分子物种芳香性的理论方法。化学合作研究奖（CRC）授予致力于广泛化学兴趣问题的跨学科科学家团队。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.
