CAREER: Soft Chemical Synthesis of Porous Materials Based on Cluster-Network Structures

9701507斯坦金属多阴阳离子团簇将被用作构建块(或作为金属前体)来合成扩展的无机-有机网络结构，以设计新的功能材料类别。将使用表面活性剂将团簇预先组织成二维和三维结构，以优化连接的团簇排列；将使用盐凝胶反应将预先组织的盐结构转化为高比表面积介孔材料，并与Argonne National Labs合作研究盐凝胶反应；将开发通过氢键、配位聚合和共价键通过有机连接器连接无机团簇的方法；将优化的连接机制与模板技术相结合，以产生具有可访问空隙的有序结构。基于团簇网络结构的新型功能多孔材料将被设计成具有空隙的空间，用于催化、分离、传感、光学或电子领域。将这些当前高度优先的材料研究挑战与这一职业计划的教育课程相结合，将导致学生在日益相关的领域进行培训，从而在促进科学和技术进步的同时改善学生的就业前景。***

9701507 Stein Metal polyanion or -cation clusters will be used as building blocks (or as metal precursors) to synthesize extended inorganic-organic network structures to design new classes of functional materials. The clusters will be preorganized in two- and three-dimensional structures using surfactants to optimize the cluster arrangements for linking; salt-gel reactions will be used to convert the pre-organized salt structures into high surface area mesoporous materials, with the salt-gel reactions studied in collaboration with Argonne National Labs; methods for the linkage of the inorganic clusters by organic connectors through hydrogen bonding, coordination polymerization, and covalent bonding will be developed; and optimized linking mechanisms will be combined with templating techniques to produce well-ordered structures with accessible void spaces. %%% New classes of functional porous materials based on cluster-network structures will be designed with void spaces for applications in catalysis, separations, sensing, optics or electronics. Integrating these current high-priority materials research challenges with the educational curriculum of this CAREER Program results in the training of students in areas of growing relevancy thereby advancing science and technology while improving job prospects for students. ***
