The Interplay of Recognition and Redox Processes. Electronically Controlled Devices and Surfaces

这个项目旨在探索识别和氧化还原过程的相互作用，从主客体化学领域扩展到自组装单层表面（SAM）的竞技场的观察。 组装在金表面上，这些SAM的将受到各种表征方法，包括掠射角红外光谱和循环伏安法。 表面的化学改性将提供具有结合特定客体分子的能力的氧化还原官能化部分。 随后的氧化还原化学将进行研究，以评估制造这样的设备作为一个分子“穿梭”的可行性，并探索控制表面特性，如电荷和疏水性/亲。 最终，电子响应材料和设备的创建可能是可能的。有了这个奖项，有机和高分子化学计划支持马萨诸塞州大学阿默斯特分校的文森特·罗特罗教授的研究。 Rotello教授的研究涉及在分子水平上合理设计表面，使用具有电活性的分子组装。 在这些实验中确定的原理可以在基于具有响应电刺激的预定结构和特性的表面的受控形成的新电子设备中找到应用。

This project seeks to explore the interplay of recognition and redox processes, extending observations from the realm of host-guest chemistry into the arena of self-assembled monolayer surfaces (SAM's). Assembled on a gold surface, these SAM's will be subject to a variety of characterization methods including grazing angle infrared spectroscopy and cyclic voltammetry. Chemical modification of the surface will provide redox-functionalized moieties with the capability of binding specific guest molecules. Subsequent redox chemistry will be studied in order to assess the feasibility of fabricating such devices as a molecular "shuttle" and to explore control of surface properties such as charge and hydrophobicity/philicity. Ultimately, the creation of electronically responsive materials and devices may be possible.With this Award, the Organic and Macromolecular Chemistry Program supports the research of Professor Vincent Rotello of the University of Massachusetts at Amherst. Professor Rotello's research involves the rational design of surfaces on a molecular level, using molecular assemblies that are electrically active. The principles that are identified in these experiments may find applications in new electronic devices based on the controlled formation of surfaces with predetermined structures and properties that respond to electrical stimuli.
