9501716 Collard Demand for smaller, more versatile electronic and opto-electronic devices continues to grow in order to increase packing density, efficiency and operational speed. The search for smaller and smaller devices has now reached the final frontier, the molecular scale. Further reduction in device size must occur at a level which addresses ensembles of molecules, or, more intriguing, discrete molecules. Through the use of scanning probe microscopic techniques and with novel molecular building blocks of pi-conjugated polymers that have already been synthesized, we propose to create defined, robust, and functional nanostructures which will test the limits of ultraminiaturization. This approach relies on the modification of substrates with monolayers of monomers that serve as templates for polymer deposition. The research program will provide insight into approaches for integration and nanofabrication of various electronic materials and will furnish materials and methods that provide precise control over the interfacial behavior of composite systems relevant to the electronics industry. %%% In the long term, organic nano-architectures promise great flexibility in the design of microcircuitry elements and quantum wave devices. The key issues to be addressed in this research include: What materials can be used to fabricate micro- and nanostructures; how can nanoscale features be produced; what are the limits of feature dimensions, and what are the stability and properties of these features? We are currently involved in a number of programs at Georgia Tech and in the Atlanta area to increase the involvement of students in technical education, including programs for minorities, women, and precollege students. Through an undergraduate outreach program to science museums we are developing illustrative interactive chemistry exhibits, and a vibrant demonstrat ion and workshop program. Curriculum development activities include development of an advanced organic chemistry course based almost entirely on problem solving, introduction of a polymer chemistry course, and development of interdisciplinary laboratory experiments. ***

小行星9501716 对更小、更通用的电子和光电器件的需求持续增长，以提高封装密度、效率和操作速度。对越来越小的设备的研究现在已经到达了最后的前沿，即分子尺度。 器件尺寸的进一步减小必须在解决分子集合或更有趣的离散分子的水平上发生。通过使用扫描探针显微技术 和 具有新颖的分子结构 块 已经合成的π共轭聚合物，我们建议创建定义的，鲁棒的，和功能性的纳米结构，这将测试超小型化的极限。这种方法依赖于用单体的单层修饰基底，所述单体的单层用作聚合物沉积的模板。 该研究计划将提供深入了解方法 用于各种电子材料的集成和纳米加工，并将提供对与电子工业相关的复合系统的界面行为提供精确控制的材料和方法。 从长远来看，有机纳米结构在微电路元件和量子波器件的设计中具有很大的灵活性。 在这项研究中要解决的关键问题包括：什么材料可以用来制造微米和纳米结构;如何可以产生纳米尺度的功能;什么是功能尺寸的限制，以及这些功能的稳定性和属性是什么？ 我们目前参与了格鲁吉亚理工学院和亚特兰大地区的一些项目，以增加学生对技术教育的参与，包括少数民族，妇女和 大学预科学生 通过一个本科生拓展项目 对于科学博物馆，我们正在开发说明性的互动化学展品，以及一个充满活力的演示和研讨会计划。 课程开发活动 包括开发几乎完全基于问题解决高级有机化学课程，引入聚合物化学课程， 和 发展 的 跨学科 实验室实验 ***
