Organized Polymer Assemblies on Conducting and Semiconducting Surfaces

目前，电光接口等高科技领域的进步受到新材料制造和加工方法的限制。例如，光学开关需要与复合分子的极轴对齐的材料。最近报道了利用新的合成方法和技术在表面合成高取向薄膜材料。这些研究代表了一项重大计划的开始，该计划将导致具有重大实际应用的独特材料。在α -氨基酸肽领域，这些材料在光稳定、电光器件中的实际应用具有很大的潜力。此外，一系列其他聚合物很可能以新的形式被制造成表面上的薄膜。概括地说，这个项目的目标是：1。制备：详细研究α -氨基酸肽在金属和非金属表面有序排列的制备方法，包括用于构建纳米级结构的光刻技术；2. 物理表征：扩展这些肽层性质的知识，特别是因为它们与它们不寻常的，高度极性的性质有关；3. 扩展：研究其他聚合物系统对表面有序生长的适用性，目的是制备迄今为止从未研究过的新型薄膜。作为这项研究的结果，将开发出由α -氨基酸制备新型、高取向薄膜的方法。这些薄膜是构建下一代光电器件的光开关的有希望的候选者。

9322040 Whitesell Advances in high technology areas such as electrooptical interfaces are currently limited by methods for fabrication and processing of new materials. For example, optical switches require materials with alignment of the polar axis of the composite molecules. The synthesis of highly oriented materials as thin films on surfaces using new synthetic methods and techniques was recently reported. These studies represent the beginning of a major program leading to unique materials with major practical applications. In the area of alpha-amino acid peptides there is a great potential for practical applications of these materials in photostable, electrooptical devices. Furthermore, it is likely that a range of other polymers can be fabricated in new forms as thin films on surfaces. Broadly stated, the goals of this program are: 1. Fabrication: to study in detail ways of preparing alpha- amino acid peptides as ordered arrays on metal and non-metal surfaces, including photolithographic techniques for the construction of nanoscale structures; 2. Physical characterization: to expand knowledge of the properties of these peptide layers, especially as they relate to their unusual, highly polar nature; 3. Extensions: to examine other polymer systems for applicability to ordered growth on surfaces, with the aim of preparing novel thin films heretofore never examined. %%% As a result of this research, methods of fabrication novel, highly oriented thin films from alpha-amino acids will be developed. The films are promising candidates for the construction of optical switches for the next generation of electrooptical devices.
