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

这个项目试图探索识别和氧化还原过程的相互作用，将观察从主-客体化学领域扩展到自组装单层表面(SAM)的领域。这些组装在金表面的SAM将受到包括掠射角红外光谱和循环伏安在内的各种表征方法的影响。表面的化学修饰将为氧化还原官能化的部分提供结合特定客体分子的能力。随后将研究氧化还原化学，以评估制造分子“航天飞机”等器件的可行性，并探索对表面性质的控制，如电荷和疏水性/亲水性。有了这个奖项，有机化学和高分子化学项目支持了马萨诸塞大学阿默斯特分校文森特·罗特洛教授的研究。罗特洛教授的研究涉及在分子水平上合理设计表面，使用具有电子活性的分子组装。在这些实验中确定的原理可能会在新的电子设备中找到应用，这些新的电子设备基于对电刺激做出反应的具有预定结构和属性的表面的受控形成。

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.
