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.

该奖项在印第安纳大学化学系的Malcolm H. Chisholm博士（印第安纳大学）的无机，生物有机和有机金属化学计划中支持对含有金属金属多键的化合物的研究。将进行五个调查领域：（1）合成新核化合物及其在合成同核和异量化簇化合物中的阐述；（2）阐明这些化合物的替代反应的详细机制，以建立一般趋势；（3）探索C-X多键和M-M多键之间的机理和多发性氧反应的效用；（4）共价连接的双核复合物的二聚体及其物理化学特性的研究以及小的低聚物作为高级低聚物和聚合物的模型；（5）关于其对电子传递的各向异性特性和非线性光学响应的各向异性特性，在有序的组件（例如1-D聚合物，液晶相和单晶体）中，M-M多键的性能的制备和研究。用于簇和链条作为簇和链条具有有用的电子，磁性和光学特性，并且是Catcectect的重要性。这项基本调查将以系统的方式探索新阵列及其特性的综合。学生将有机会学习广泛的合成和物理方法，并将研究扩展到材料研究中。
