Supramolecular Chemistry of Gases

通过这个奖项，有机和大分子化学项目支持德克萨斯大学阿灵顿分校的Dimitry Rudkevich，他的研究被提议应用分子识别、超分子化学和动态、可逆共价化学的原理和技术来创造受体分子和材料，用于重要温室气体的良性化学固定。纳米结构和气体动态材料也将被设计。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，包括杯芳烃笼和纳米管；SO2气体的超分子活化和固定，以及CO2的超分子固定，从而产生可切换的功能纳米结构，即所谓的双发电机。这是基于二氧化碳和胺的可逆化学反应，也涉及到氢键。拟议中的项目将继续在气体分子识别方面发挥领导作用，并证明温室气体现在可以用作分子和超分子的基石。该奖项由有机和大分子化学项目颁发给德克萨斯大学阿灵顿分校的迪米特里·鲁德克维奇教授，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建筑材料。考虑到气体在环境中的巨大意义，该计划提供了创造环保材料的方法。Rudkevich教授将继续发表关于气体超分子化学的一般性评论，从而接触到广泛的化学读者并吸引他们进入该领域。PI实验室的出版物已经在《科学》、《化学》杂志上发表。和其他杂志，也在互联网上。自5年前发起以来，已有数十名高中生、本科生、研究生和博士后参与其中。由于气体在大学教育中的重要性在很大程度上被忽视，因此正在为本科生/研究生开设一门关于超分子化学和气体技术的跨学科课程。来自非裔美国人、西班牙裔美国人、亚裔美国人和女学生等代表性不足群体的10多名学生积极参与了PI小组的研究。与多个研究中心就气体的超分子技术和纳米技术展开合作。这些机构包括犹他大学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，以及法国蒙彼利埃的欧洲膜研究所和日本福井大学。

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).
