Organic Electrochemistry

该项目属于分析和表面化学的一般领域，以及有机电化学的子领域。在这项为期三年的持续资助期间，米勒教授和他的学生将合成各种线型和螺旋型聚并苯，其中包含两个或更多个电致发光材料、单分散的噻吩齐聚体和多个电致发光材料。然后，他们将研究这些实体的氧化还原化学，以及由此产生的离子自由基和多离子。这些自由基离子和多离子物种的研究将特别强调了解电子在共轭体系中的局域化，以及局域有序对这些物质的聚集、电子和手性性质的影响。这项研究建立在米勒小组在国家科学基金会资助车-8717540的支持下所取得的成就的基础上。这一研究项目的结果将扩展目前对电子离域的理解，并对分子材料的发展领域做出重大贡献。此外，适用于激光的新的红外和近红外染料可以直接从这项工作中进化出来。

This project is in the general area of analytical and surface chemistry and in the subfield of organic electrochemistry. During the tenure of this three-year continuing grant, Professor Miller and his students will synthesize various linear and helical polyacenes containing two or more electrophores, monodisperse thiophene oligomers, and polyelectrophores. They will then study the redox chemistry of these entities and the resulting ion radicals and poly-ions. These radical ion and poly-ion species will be investigated with particular emphasis on understanding electron localization in conjugated systems and the effects of local ordering on the aggregate electronic and chiroptical properties of these substances. This research builds upon accomplishments of the Miller group under the aegis of NSF grant CHE-8717540. %%% Results from this research project will extend current understanding of electron delocalization and contribute significantly to the developing area of molecular materials. Additionally, new infrared and near-infrared dyes suitable for use in lasers could evolve directly from this work.
