Surface-Directed Assemblies of Complex Nanoscale Materials: Fabrication, Structure, Dynamics, and their Applications

在分析和表面化学项目的支持下，伊利诺伊大学厄巴纳-香槟分校的Nuzzo教授和他的同事们正在研究自组装的详细机制和用于材料纳米图案化的软光刻方法。 他们正在努力开发表征这些纳米图案化材料的新方法，并正在探索自组装和改性层生长的机制。 工作的一个方面集中在液晶材料的动力学。 另一方面涉及贴花转印光刻，第三方面涉及微流体耗尽光刻。 这第三个研究领域主要应用于表面上的蛋白质图案。 这些研究的结果有望提高我们对这些新兴技术的电光，分子电子器件和传感器的制造的基本理解。有机薄膜和单层的自组装和生长的详细了解是必不可少的新兴技术的发展，用于制造有机电子和电光器件。 使用光谱方法，这些复杂的材料系统正在进行表征和开发。正在探索用于生产纳米图案材料的光刻方法，随后将其应用于电子材料加工。

AbstractCHE-0402420Nuzzo/IllinoisWith the support of the Analytical and Surface Chemistry Program, Professor Nuzzo and his colleagues at the University of Illinois at Urbana-Champaign are investigating the detailed mechanisms of self assembly and soft lithographic methods for nano-patterning of materials. They are working to develop new methods for characterizing these nano-patterned materials, and are exploring the mechanisms of self-assembly and growth of the modified layers. One aspect of the work concentrates on the dynamics of liquid crystalline materials. Another aspect deals with decal transfer lithography, and a third with microfluidic depletion lithography. This third area of study is applied primarily to protein patterning on surfaces. Results of these investigations promise to enhance our fundamental understanding of these emerging technologies for the fabrication of electrooptic, molecular electronic devices, and sensors.The detailed understanding of self-assembly and growth of organic thin films and monolayers is essential to the development of emerging technologies for the fabrication of organic electronic and electrooptical devices. Using spectroscopic methods, these complex materials systems are being characterized and developed. Lithographic methods for the production of nanopatterned materials are being explored, with subsequent application in electronic materials processing.
