Surface Oriented Organic Polymers

这项SGER研究将直接回答有关控制表面上聚合物分子取向以及这种表面结合聚合物层的化学和物理性质的基本科学问题。重点关注的具体问题是：如何在距离底层相当远的地方保持表面隐含的方向性在结合聚合物的方向上？与溶液态和固体态（但不是唯一取向）相比，这种束缚层的独特性质是什么？这些材料的性质是如何被其他分子的存在所改变的？这种改变是否可逆？如果可逆，其速率是多少？这个基础科学项目旨在收集必要的种子信息，在此基础上，可以建立光学开关和分子传感器的潜在应用。

This SGER research will be directed to answering fundamental, scientific matters concerning the control of orientation of polymer molecules on surfaces and the chemical and physical properties of such surface-bound polymer layers. Specific questions upon which attention will be focused are: How can the directionality implicit in a surface be preserved in the orientation of a bound polymer at substantial distances from the underlying? What are the unique properties of such bound layers as contrasted with both the solution and solid (but not uniquely oriented) states? How are the properties of such materials altered by the presence of other molecules, and are such changes reversible, at if so, at what rate? This fundamental science program is intended to gather the necessary seed information upon which potential applications applications in optical switches and molecular sensors can be built.
