Cluster-Expanded Solids: A Strategy for Assembling Functional Porous Materials

该奖项授予了加州大学伯克利分校化学系Jeffrey R. Long教授，他致力于利用多核氰金属酸盐作为构建块，合成和表征扩展团簇，以制造开放框架和微孔材料。这些由溶液化学制备的团簇，在脱水后将产生具有大空隙体积的多孔材料，并且不会失去结构完整性。具有边缘桥接八面体几何形状的簇核将由钴，锆和其他金属氯化物与硼或铍制备，用于离子交换反应，多孔磁铁和化学传感器的潜在应用。此外，孔隙的包合物性质将根据具体的应用进行修改。参与该项目的学生将学习先进的合成方法，并获得与纳米科学和工程相关的化学、材料和物理的跨学科经验。具有大空隙空间的多孔簇，开放框架和微孔固体将是坚固的和可重复使用的。这些团簇可以用包合基团功能化，用于不同的应用，如离子交换反应、用于分离的多孔磁体和用于挥发性有机化合物的传感器。此外，参与该项目的学生将获得固态和无机化学的经验。

This award to the University of California at Berkeley supports the work of Professor Jeffrey R. Long, Department of Chemistry, aimed at the synthesis and characterization of expanded clusters using multinuclear cyanometalates as building blocks to make open frame and microporous materials. These clusters prepared by solution chemistry, after dehydration will result in porous materials with large void volumes and without loss of structural integrity. Cluster-cores with edge-bridged octahedral geometry will be prepared from cobalt, zirconium and other metal chlorides with boron or beryllium for potential applications in ion exchange reactions, porous magnets and chemical sensors. In addition, inclusion properties of pores will be modified for specific applications. Students involved in this project will learn advanced synthetic methods and will gain interdisciplinary experience in chemistry, materials, and physics relevant to nanoscience and engineering.Porous clusters with large void spaces, open-framework and microporous solids will be robust and reusable. These clusters may be functionalized with inclusion groups for different applications such as ion exchange reactions, porous magnets for separations, and sensors for volatile organic compounds. In addition, students involved in the project will gain experience in solid state and inorganic chemistry.
