Main Group Rings, Clusters, and Assemblies

阿兰·考利博士，德克萨斯大学奥斯汀分校化学系，由化学部无机、生物无机和有机金属计划支持，主要研究主基团环、簇合物和组装体。将制备几个具有第13族元素的新的不饱和环系，其中一些可能作为开环复分解聚合(ROMP)的候选者。将研究杂氮二烯作为热或光化学来源的潜力，例如金属间化合物材料。将13族-13族键结合到堆积结构中的双环体系的组装将被研究其潜在的有趣的电和/或磁性质。还将寻求各种阴离子识别方法，包括结合第13族或第14族元素的多齿路易斯酸组件，并将开发形成较重第13族元素的簇状和笼状化合物的新方法。将制备和研究主要族元素(硼、铝、镓和铟)与碳环系统和彼此之间的新组合。除了对这些环的结构和成键描述的内在兴趣外，这些化合物还可能成为具有新的电和/或磁性能的新的聚合物和金属间化合物材料的前体。较大的环系适合于阴离子的选择性和可逆结合，因此在阴离子传输和均相催化中具有潜在的应用

Dr. Alan Cowley, Department of Chemistry, University of Texas at Austin, is supported by the Inorganic, Bioinorganic, and Organometallic Program of the Chemistry Division for studies of main group rings, clusters, and assemblies. Several new unsaturated ring systems featuring the group 13 elements will be prepared, some with potential as candidates for ring opening metathesis polymerization (ROMP). Heteronorbornadienes will be investigated for their potential as thermal or photochemical sources of, for example, intermetallic materials. Assembly of bicyclic ring systems that incorporate group 13 - group 13 bonds into stacked architectures will be investigated for their potentially interesting electrical and/or magnetic properties. Various approaches to anion recognition, including multidentate Lewis acid assemblies that incorporate group 13 or 14 elements, will also be pursued, and new approaches to the formation of cluster and cage-type compounds of the heavier group 13 elements will be developed. New combinations of main group elements (boron, aluminum, gallium, and indium) with carbon ring systems and with one another, will be prepared and investigated. Apart from the intrinsic interest in the structures and bonding descriptions of these rings, these compounds have potential as precursors to new polymeric and intermetallic materials with novel electrical and/or magnetic properties. The larger ring systems are appropriate for the selective and reversible binding of anions, and thus have potential applications in anion transport and homogeneous catalysis
