This award in the Inorganic, Bioinorganic and Organometallic program supports research on the development of new crystal engineering protocols and their application to the assembly of synthetic zeolite analogs and molecular-based magnetic materials by Professor Christer Aakeroy of the Department of Chemistry at the Kansas State University. This will be accomplished by constructing extended hybrid inorganic/organic architectures using hydrogen-bond interactions and custom-designed ligands, notably substituted pyridines, triazines and pyrimidines. The latter will be used in conjunction with divalent Cu, Co, Mn and Ni ions to produce the molecular magnets. The compounds will be characterized by means of IR, NMR, DSC and X-ray diffraction. The utility of the catalytic support compounds will be examined using the hydrogenation of small alkenes as a model reaction, and the magnetic properties of the metal pyrimidines by means of a SQUID magnetometer.The goal of this research is to develop a fundamental understanding of the principles of crystal engineering based on molecular self-assembly and to use these principles to synthesize materials with useful physical properties. In particular, catalytic supports and molecular magnets will be produced which have important applications in the petrochemical and information technology industries. The students involved in this project will learn a breadth of skills in both synthesis and instrumental methods, and gain experience which links fundamental chemistry with commercial use.

该奖项在无机，生物有机和有机金属计划中支持有关新的水晶工程方案的发展的研究，并将其应用于堪萨斯州立大学化学系教授Christer Aakeroy教授的合成沸石类似物和基于分子的磁性材料。这将通过使用氢键相互作用和定制设计的配体，尤其是取代的吡啶，三环和吡啶胺来构建扩展的混合无机/有机体系结构来实现。后者将与Divalent Cu，Co，Mn和Ni离子一起使用以产生分子磁体。这些化合物将通过IR，NMR，DSC和X射线衍射的方式来表征。将使用小烷烃作为模型反应来检查催化载体化合物的效用，并通过鱿鱼磁力计的金属嘧啶的磁性特性。这项研究的目的是建立基于基于分子自构和使用这些原理的晶体工程原理的基本理解，以将这些原理与这些原理进行物理材料，以实现物理特性。特别是，将生产催化载体和分子磁铁，在石化和信息技术行业中具有重要的应用。参与该项目的学生将学习合成和乐器方法方面的广泛技能，并获得将基本化学与商业用途联系起来的经验。
