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

这一奖项授予加州大学伯克利分校化学系Jeffrey R.Long教授，旨在利用多核氰酸盐作为构建块合成和表征扩展簇合物，以制造开放框架和微孔材料。这些通过溶液化学方法制备的团簇，经过脱水后，将得到具有大孔洞体积且不损失结构完整性的多孔材料。具有边缘桥联八面体几何结构的团簇核心将由钴、锆和其他金属氯化物与硼或铍制备，在离子交换反应、多孔磁体和化学传感器中具有潜在的应用。此外，孔的包裹体属性将根据特定应用进行修改。参与这个项目的学生将学习先进的合成方法，并将获得与纳米科学和工程相关的化学、材料和物理方面的跨学科经验。具有大空隙空间、开放框架和微孔固体的多孔团簇将是坚固和可重复使用的。这些簇合物可以通过包合基团来功能化，以用于不同的应用，例如离子交换反应、用于分离的多孔磁体和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方面的经验。

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.
