Synthesis and properties of metal organic frameworks

为目标应用开发新材料需要设计、执行和评估的迭代周期。该提议涉及一类多孔化合物，金属有机框架（MOFs），其以有序、多孔和易于系统结构变化而闻名。这种顺序转化为在原子水平上评估结构的能力。再加上系统变化的丰富选项，这是一个强大的设计范例。提出了三个子方案，第一个提出了新的基本构建块和它们的自组装成集群或胶囊物种。后两个项目涉及利用从项目一中获得的分子理解并将其应用于天然气储存（最终目标是汽车车载储存）和更好的质子导体（最终用于更好的氢燃料电池膜）。建议的建筑单元是一种新的方法，提供了更合理的设计选择，并证明了提高目前阿喀琉斯之踵的材料类稳定性的潜力。

Development of new materials for targeted applications requires an iterative cycle of design, execution, and assessment. This proposal concerns a class of porous compounds, metal organic frameworks (MOFs) that are renowned for being ordered, porous and amenable to systematic structure variation. The order translates to the ability to assess structure at the atomic level. Coupled with the abundant options for systematic variation, this is a powerful design paradigm. Three sub-proposals are presented, the first proposes new basic building blocks and their self-assembly into cluster or capsular species. The latter two projects concern taking the molecular understanding obtained from Project one and applying it towards natural gas storage (ultimately with goals of on-board storage for automobiles) and better proton conductors (ultimately for better hydrogen fuel cell membranes). The building units proposed are a new approach and offer more rational design options as well as demonstrated potential to improve stability of the class of materials, presently an Achilles' heel.
