项目摘要

In this project funded by the Macromolecular, Supramolecular and Nanochemistry Program of the Chemistry Division, Prof. Peter J. Stang of the University of Utah investigates coordination-driven self-assembly of 2D metallacycles and 3D metallacages. Specifically, heterligated Pt-complexes, involving carboxylate and pyridyl ligands, will be studied that allow the formation of a greater variety and more complex supramolecular assemblies. Multi-component self-assembly, as well as the interconversion of homoligated pyridyl architectures with heteroligated systems, will be examined. The use of flexible ligands and heteroligated, flexible multi-component assemblies will be investigated. This research will advance our fundamental understanding of how simple molecules spontaneously self-assemble into complex nanoscale systems. This work could have significant impact upon nanoscience and nanotechnology and, in particular, future "bottom up" manufacturing. It may also provide new materials with novel properties and functions such as sensors, catalysts, etc. of importance in the chemical industry. The broader impact also involves training postdoctoral researchers and graduate and undergraduate students in supramolecular self-assembly. These researchers will also be mentored in the dissemination of research results via presentations at major conferences and publications in premier peer reviewed, scientific journals.

在这个由化学系大分子、超分子和纳米化学项目资助的项目中，犹他州大学的Peter J. Stang教授研究了2D金属环和3D金属笼的配位驱动自组装。具体而言，heterligated铂配合物，涉及羧酸盐和吡啶基配体，将进行研究，允许形成一个更大的品种和更复杂的超分子组装。多组分自组装，以及homoligated吡啶结构与heteroligated系统的相互转换，将被检查。使用灵活的配体和heteroligated，灵活的多组分组件将进行调查。这项研究将推进我们对简单分子如何自发自组装成复杂纳米系统的基本理解。这项工作可能会对纳米科学和纳米技术，特别是未来的“自下而上”的制造业产生重大影响。它还可以提供具有新特性和功能的新材料，如化学工业中重要的传感器，催化剂等。更广泛的影响还包括培训博士后研究人员和研究生和本科生在超分子自组装。这些研究人员还将通过在主要会议上的演讲和在一流的同行评审科学期刊上的出版物传播研究成果。
