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

在分析和表面化学计划的支持下，伊利诺伊大学厄巴纳香槟分校的努佐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。他们正在努力开发新的方法来表征这些纳米图案材料，并探索修饰层的自组装和生长机制。这项工作的一个方面集中在液晶材料的动力学上。另一个方面涉及贴花转移光刻，第三个方面涉及微流控耗尽光刻。这第三个研究领域主要应用于表面的蛋白质图案化。这些研究结果有助于加深我们对电光、分子电子器件和传感器等新兴技术的基本了解。对有机薄膜和单分子膜的自组装和生长的详细了解对于发展有机电子和电光器件的新兴技术是至关重要的。利用光谱方法，正在对这些复杂的材料体系进行表征和开发。人们正在探索用于生产纳米颗粒材料的光刻方法，并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.
