The project entitled CAREER: Functional Nanoscale Architectures by Self-Assembly aims to educate students in chemical approaches to nanoscience through an integration of educational and research objectives. The thrust of the research is to design new types of monodisperse oligomers of overcrowded aromatics that can fold themselves into well-defined conformations. The synthesis of these multimers will be expanded to create monodisperse oligomers 8 to 20 subunits long. Due to their unique structure these oligomers could provide new motifs for self-assembly in lipid bilayers and in bulk. These oligomers will be investigated as one dimensional semiconductors and nanoscale piezoelectric elements. Integrated within the research plan, is begin to modernize the chemistry curriculum to have the chemical elements of nanotechnology. Proposed is an advanced organic chemistry lab for junior level undergraduates that would use organic synthesis and self-assembly as a tool to teach the concepts of polymer structure/function relationships, self-assembly/surface patterning, and liquid crystallinity. Some of the web-based, multimedia modules and nanoscience laboratories created for undergraduate education will be used to reach underrepresented groups in New York area high schools.This project will educate future scientists and engineers through a chemistry program that integrates both educational and research objectives. The educational objectives will create web-based, multimedia modules and laboratory experiments to begin the modernization and revitalization of the undergraduate chemistry curriculum. Some of the elements used in the undergraduate curriculum reform will be used to reach underrepresented groups in New York area high schools. The research objectives in this proposal will train graduate and undergraduate students in cutting-edge, interdisciplinary research that designs, synthesizes, and studies new molecules that self-organize into novel structures. These unique oligomers could act as nanoscale wires, switches, and devices for energy conversion. This proposal is co-funded by the Division of Materials Research and the Chemistry Division.

该项目名为“职业：自组装的功能纳米级架构”，旨在通过教育和研究目标的整合，教育学生使用纳米科学的化学方法。研究的重点是设计新型的单分散的过度拥挤的芳烃低聚物，可以折叠成明确的构象。这些多聚物的合成将扩展到8到20个亚基长的单分散低聚物。由于其独特的结构，这些低聚物可以为脂质双分子层和散装的自组装提供新的基序。这些低聚物将作为一维半导体和纳米级压电元件进行研究。结合研究计划，开始使化学课程现代化，使其具有纳米技术的化学元素。本课程是一门高级有机化学实验课，面向初级本科生，将以有机合成和自组装为工具，教授聚合物结构/功能关系、自组装/表面图形和液态结晶的概念。一些为本科教育创建的基于网络的多媒体模块和纳米科学实验室将被用来接触纽约地区高中中代表性不足的群体。这个项目将通过一个结合了教育和研究目标的化学项目来培养未来的科学家和工程师。教育目标将创建基于网络的多媒体模块和实验室实验，以开始本科化学课程的现代化和振兴。本科课程改革中使用的一些元素将用于接触纽约地区高中中代表性不足的群体。本提案的研究目标将培养研究生和本科生进行尖端的跨学科研究，设计、合成和研究自组织成新颖结构的新分子。这些独特的低聚物可以用作纳米级的电线、开关和能量转换设备。本提案由材料研究部和化学部共同资助。
