Design and Synthesis of Porous Metal-Organic Frameworks

这个项目的目的是开发从分子构建块设计和合成金属有机材料的策略。具体来说，金属-羧酸盐簇将通过有机连接组装成多孔支架或金属-有机框架（MOFs）。这些mof具有显著的孔隙度，可以达到最多孔的沸石的5倍。这种方法的通用性将在大量不同长度和功能的簇和有机链接中进行测试和开发，以便制备mof，其中可以改变其度量和化学功能，而不改变其底层拓扑结构（或骨干结构），同时保持框架的周期性。这个项目为学生和博士后提供了无与伦比的机会来学习与溶液化学和固态化学相关的化学和物理技术，这两个领域传统上是分开实践的。在智力层面上，学生体验到设计和发现之间必须存在的必要协同作用，使用各种智力工具，从数学和网络枚举到所制备材料的包合化学的合成、表征和研究。晶体多孔材料在石油裂解、催化、分离和离子交换过程中发挥着重要作用，对全球经济产生了巨大的影响。事实上，多孔材料在全球经济中占据了（大约）3500亿美元的份额。本项目旨在研究一种新型多孔材料的设计和合成，其中无机和有机成分可以随意变化，以执行高度特定的功能。例如，能够在环境条件下储存用于移动电子设备和汽车燃料的氢气和天然气的材料将被追求。这些应用将使更多的环保燃料进入主流使用。这个小组已经开始与工业界合作，设计用于手机和笔记本电脑的金属有机框架的储氢盒。在这个项目下将发展的化学方法对学生和青年科学家的教育有许多意义。例如，研究人员现在正在参与一个项目，鼓励跨多个学科的思考和工作，从材料合成和表征到应用开发

The aim of this project is to develop strategies for the design and synthesis of metal-organic materials from molecular building blocks. Specifically, metal-carboxylate clusters will be assembled by organic links into porous scaffolds or metal-organic frameworks (MOFs). These MOFs have been shown to have remarkable porosities that can reach up to five times those observed in the most porous zeolites. The generality of this approach will be tested and developed for a large number clusters and organic links of varying lengths and functionalities in order to prepare MOFs in which it is possible to change their metrics and chemical functionalities without changing their underlying topology (or backbone structure) still maintaining periodicity of the framework. This project provides unparalleled opportunities for students and postdoctoral fellows to learn chemical and physical techniques associated with both solution and solid-state chemistries, areas traditionally practiced separately. On the intellectual level, students experience the necessary synergy that must exist between design and discovery using diverse intellectual tools ranging from mathematics and the enumeration of networks to synthesis, characterization and study of the inclusion chemistry of the materials prepared.%%%Crystalline porous materials have a tremendous impact on the global economy, as they are useful in petroleum cracking, catalysis, separation and ion exchange processes. Indeed porous materials represent a (roughly) US$350 billion segment of the global economy. This project is aimed at studying the design and synthesis of new kind of porous materials in which the inorganic and organic components can be varied at will to perform highly specific function. For example, materials capable of storing hydrogen and natural gas at ambient conditions for use in mobile electronics and automobile fueling will be pursued. These applications will bring more environmentally benign fuels into mainstream use. Already, this group is establishing cooperation with industry to design hydrogen storage cartridges that employ metal-organic frameworks for use in mobile phones and laptop computers. The chemical approach that will be developed under this project has a number of implications for the education of students and young scientists. For example, researchers are now participating in a program that encourages thinking and working across several disciplines, and from materials synthesis and characterization through the development of applications.***
