该项目由分析和表面化学项目支持，研究的重点是开发新的制备方法，以制造用于光学和电子元件的新型有机薄膜组件。阿姆斯特朗教授和他在亚利桑那大学的学生将使用综合方法合成和表征这些薄膜系统。有机分子束外延（OMBE）和Langmuir-Blodgett （L-B）方法将被用于在各种衬底表面沉积薄膜。利用OMBE制备高发光染料的有机薄膜将通过各种光谱和晶体学方法进行表征，以了解其结构和组成在其最终用作微电路元件中的作用。将利用L-B技术制备一些酞菁衍生物的双层和多层薄膜。研究人员正在研究这些薄膜在微电路和场效应晶体管（FET）器件方面的未来应用。有机分子薄膜的受控生长是一个非常有趣的领域，因为它在分子电子器件的创造中具有潜在的影响。新的制备和表征策略的发展是该技术发展的重要组成部分。阿姆斯特朗教授和他在亚利桑那大学的学生将应用新的合成方法和一系列光谱技术来深入了解有机薄膜的基本电子和光学特性。在这里进行的分子薄膜系统的合成和表征方面的结合将与有机薄膜的广泛应用有关。

The development of new preparation methodologies for the creation of novel organic thin film assemblies for use as optical and electronic elements is the focus of the research in this project supported by the Analytical and Surface Chemistry Program. Professor Armstrong and his students at the University of Arizona will use a comprehensive approach of synthesis and characterization of these thin film systems. Organic molecular beam epitaxy (OMBE) and Langmuir-Blodgett (L-B) approaches will be employed to deposit films on a variety of substrate surfaces. The preparation of organic films of highly luminescent dyes by OMBE will be characterized through a variety of spectroscopic and crystallographic methods to gain understanding into the role of structure and composition in their ultimate use as microcircuitry elements. Bilayer and multilayer films of a number of phthalocyanine derivatives will be prepared using the L-B technique. The films are being investigated for future applications as microcircuitry and field effect transistor (FET) devices. The controlled growth of organic molecular thin films is an area of intense interest due to its potential impact in the creation of molecular electronic devices. The development of new preparation and characterization strategies is a vital component in the evolution of this technology. Professor Armstrong and his students at the University of Arizona will apply new synthetic methods and a host of spectroscopic techniques to gain insights into the fundamental electronic and optical properties of organic thin films. The combination of synthetic and characterization aspects of molecular thin film systems undertaken here will have relevance to a wide range of projected applications of organic thin films.
