With this award, the Organic and Macromolecular Chemistry Program supports Dimitry Rudkevich of the University of Texas- Arlington whose research is proposed to apply principles and techniques of molecular recognition, supramolecular chemistry and dynamic, reversible covalent chemistry to create receptor molecules and materials for benign chemical fixation of important greenhouse gases. Nanostructures and dynamic materials from gases will also be designed. Specific problems to be addressed include the design, synthesis and host-guest chemistry of NOX trapping, separating, storing and releasing molecules, including calixarene-based cages and nanotubes; supramolecular activation and fixation of SO2 gas, and supramolecular fixation of CO2, which results in switchable, functional nanostructures, so-called double dynamers. These are based on reversible chemistry of CO2 and amines and also involve hydrogen bonding. The proposed program will continue to lead efforts in molecular recognition with gases and also demonstrate that greenhouse gases can now be used as molecular and supramolecular building blocks.This award from the Organic and Macromolecular Chemistry Program supports Professor Dimitry Rudkevich of the University of Texas- Arlington whose research opens new ways for chemical utilization of atmospheric gases where greenhouse gases can now be used as building blocks. Considering the huge significance of gases in the environment, the program offers means for creating environmentally responsive materials. Professor Rudkevich will continue publishing general reviews on supramolecular chemistry of gases, thus reaching out to the broad chemistry readership and attracting them to the field. Publications from the PI's laboratory have been highlighted in Science, J. Chem. Ed. and other magazines, and also on the Internet. Since its initiation 5 years ago, his has involved dozens of high school, undergraduate, graduate and postdoctoral students. An interdisciplinary course for undergraduate/graduate students on supramolecular chemistry and technology of gases is being developed, because the significance of gases has been largely overlooked in college education. More than 10 students from underrepresented groups, such as African-Americans, Hispanic, Asian Americans, and female students have been actively involved in research in the PI's group. Collaborations have been initiated with a number of research centers on supramolecular technology and nanotechnology of gases. These include the UTA's Automation and Robotics Research Institute, Center for Green Manufacturing at The University of Alabama, Tuscaloosa, the National Energy Technology Lab at DOE, the University of Pittsburgh, as well as the Institut Europeen des Membranes in Monpellier (France) and the University of Fukui (Japan).

该奖项旨在支持德克萨斯大学阿灵顿分校的迪米特里·鲁德凯维奇，他的研究旨在应用分子识别、超分子化学和动态、可逆共价化学的原理和技术，为重要温室气体的良性化学固定创造受体分子和材料。还将设计纳米结构和来自气体的动态材料。需要解决的具体问题包括氮氧化物捕获、分离、储存和释放分子的设计、合成和主客体化学，包括基于杯芳烃的笼子和纳米管；二氧化硫气体的超分子活化和固定，以及二氧化碳的超分子固定，这导致可切换的功能纳米结构，即所谓的双发电机。它们基于二氧化碳和胺的可逆化学反应，也涉及氢键。拟议中的计划将继续引领分子识别气体的努力，并证明温室气体现在可以用作分子和超分子构建块。有机和高分子化学计划颁发的这一奖项支持德克萨斯大学阿灵顿分校的迪米特里·鲁德克维奇教授的研究，他的研究为大气气体的化学利用开辟了新的途径，温室气体现在可以用作构建块。考虑到气体在环境中的巨大意义，该计划提供了创造环境响应材料的手段。鲁德凯维奇教授将继续发表关于气体超分子化学的综述，从而接触到广泛的化学读者，并将他们吸引到该领域。来自PI实验室的出版物在《科学，J·化学》杂志上被突出显示。艾德和其他杂志，也在互联网上。自5年前启动以来，HIS已有数十名高中生、本科生、研究生和博士后参加。一门面向本科生/研究生的跨学科课程正在开发中，该课程涉及超分子化学和气体技术，因为气体的重要性在大学教育中基本上被忽视了。来自非裔美国人、西班牙裔、亚裔美国人和女性学生等代表性不足群体的10多名学生积极参与了PI的小组的研究。已经开始与一些研究中心在超分子技术和气体纳米技术方面进行合作。这些机构包括UTA的自动化和机器人研究所、塔斯卡卢萨阿拉巴马大学的绿色制造中心、美国能源部的国家能源技术实验室、匹兹堡大学，以及位于法国蒙彼利埃的欧洲膜研究所和日本的福井大学。
