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.

9322040 Whitesell在高技术领域的进展，如电光接口，目前受到新材料的制造和加工方法的限制。 例如，光学开关需要复合分子的极轴对齐的材料。 最近报道了使用新的合成方法和技术在表面上合成高度取向的材料作为薄膜。 这些研究代表了一个重大计划的开始，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，这些材料在光稳定的电光器件中的实际应用具有很大的潜力。 此外，很可能可以在表面上以薄膜的新形式制造一系列其他聚合物。 概括地说，该计划的目标是：1。 制作：详细研究在金属和非金属表面上制备α-氨基酸肽有序阵列的方法，包括构建纳米结构的纳米技术; 2. 物理特性：扩展这些肽层的性质的知识，特别是当它们涉及它们的不寻常的、高极性性质时; 3. 扩展：以制备迄今为止从未研究过的新型薄膜为目的，研究其他聚合物体系在表面上有序生长的适用性。 作为这项研究的结果，制造新的方法，高度取向的薄膜从α-氨基酸将被开发。 该薄膜是有前途的候选人，为下一代的电光器件的光开关的建设。
