Organic Poly Redox Arrays

通过这个奖项，有机和大分子化学项目支持了阿拉巴马大学塔斯卡卢萨分校化学系塞拉斯·c·布莱克斯托克博士的工作。该工作涉及合成和研究大分子有机多氧化还原阵列，包括新的非凯库勒pi系统的自旋排列，以及沿氧化还原链的电荷传输。介质对多自由基离子自旋态能量排序的影响也将被确定。平行工作将研究具有径向氧化还原梯度的新型枝状多氧化还原结构中的电荷输运。聚自由基，具有两个或多个不成对电子自旋的有机化合物，将使用电化学、核磁共振、电子自旋共振和理论计算来研究，寻找有趣的电学和磁学性质。具有氧化还原活性元素的树状结构随着从中心到外围的变化而变化，有望表现为电荷漏斗装置，并有可能在氧化还原成像介质中用作新型电荷存储纳米元件。这项工作有望为学生在合成、仪器测量和化学计算方面提供有价值的训练。

With this award the Organic and Macromolecular Chemistry program supports the work of Dr. Silas C. Blackstock in the Department of Chemistry at the University of Alabama Tuscaloosa. The work involves the synthesis and study of macromolecular organic poly redox arrays involving spin alignment in new non-Kekule pi-systems, and charge transport along redox chains. Medium effects on the energy ordering of the polyradical ion spin states will also be determined. Parallel work will investigate charge transport in new dendridic poly redox structures with radial redox gradients.Poly radicals, organic compounds with two or more unpaired electron spins, will be studied using electrochemistry, nuclear magnetic resonance, electron spin resonance, and theoretical computations, looking for interesting electrical and magnetic properties. Dendrimeric structures with redox active elements that change as one goes from the center to the periphery are expected to behave as charge funnel devices, and have a potential use as novel charge storage nano-components in redox-imaging media. The work is expected to provide valuable training for students in synthesis, instrumental measurements, and chemical computation.
