项目摘要

This award in the Inorganic, Bioinorganic, and Organometallic Chemistry Program supports research on compounds containing metal-metal multiple bonds by Dr. Malcolm H. Chisholm of the Chemistry Department, Indiana University. Five areas of investigation will be carried out: (1) synthesis of new dinuclear compounds and their elaboration in synthesis of homonuclear and heterometallic cluster compounds; (2) elucidation of the detailed mechanisms of substitution reactions of these compounds in order to establish general trends; (3) exploration of mechanisms and utility of multiredox reactions between C-X multiple bonds and M-M multiple bonds; (4) synthesis of covalently linked dimers of dinuclear complexes and the study of their physicochemical properties together with small oligomers as models for higher oligomers and polymers; and (5) the preparation and investigation of the properties of M-M multiple bonds in ordered assemblies (such as 1-D polymers, liquid crystalline phases and single crystals) with respect to their anisotropic properties of electron transfer and non-linear optical responses.Metal arrays as clusters and chains have useful electronic, magnetic, and optical properties and are also important in catalysis. This fundamental investigation will explore the synthesis of new arrays and their properties in a systematic way. Students will have opportunities to learn a broad range of synthetic and physical methods and to extend their studies into materials research.

该奖项在无机，生物无机和有机化学计划支持研究的化合物含有金属-金属多重键博士马尔科姆H。印第安纳州大学化学系的奇泽姆说。本论文的研究内容包括五个方面：（1）新型双核化合物的合成及其在同金属和异金属簇合物合成中的应用;（2）阐明这些化合物的取代反应的详细机理，以确立一般趋势;（3）探索C-X多重键和M-M多重键之间的多氧化还原反应的机理和应用;（4）共价连接的双核配合物二聚体的合成及其物理化学性质的研究，以及作为高级低聚体和聚合物模型的小分子低聚体的研究;有序组装体中M-M多重键的制备和性质研究（例如1-D聚合物，液晶相和单晶）相对于它们的电子转移和非-作为簇和链的金属阵列具有有用的电子、磁性和光学性质，并且在催化中也是重要的。这一基础研究将探索新阵列的合成及其系统的性质。学生将有机会学习广泛的合成和物理方法，并将他们的研究扩展到材料研究。
