Development of Unique Multitopic Ligands for the Syntheses of Highly Organized Multi-metallic Complexes

无机，生物无机和有机化学计划的这一奖项支持南卡罗来纳州大学的丹尼尔雷格教授设计新型的多金属配位化合物，这些化合物在固态下具有高度组织的结构，并表现出不寻常的电，物理和磁性能。这些配合物将使用一系列新的配体制备，这些配体专门设计用于与一种以上的金属结合，并含有设计用于支持超分子结构的官能团。 新的主体/客体化学基于由独特的三脚架配体如1，3，5-（CH 3）3C 6 [CH 2 OCH 2C（pz）3]3（pz=吡唑基环）和新的双配位配体的金属络合物如Fe[C5 H4 CH（pz）2]2（其基于二茂铁核的半柔性性质）形成的组装体，将成为目标。 特别重要的系统，将被调查的是自旋交叉Fe（II）N6配合物，这是复杂的可切换域，打开新的可能性，开发新的存储设备。 新型的多金属配位化合物将被合成，它们在固态下具有高度有序的结构，并表现出不同寻常的性质。 这项研究将导致新的配体的合成，专门设计成键合到一个以上的金属，并开发超分子结构和光学和磁性之间的关系不断增长的知识。 这样的材料可以通过形成新型存储器器件的基础而具有显著的潜在影响。这项研究对于培养各种教育水平的广泛培训的专家具有吸引力。事实上，PI拥有多样化的人力资源和教育发展的传统。

This award in the Inorganic, Bioinorganic and Organometallic Chemistry program supports Professor Daniel Reger at the University of South Carolina to design new types of multi-metallic coordination compounds that have highly organized structures in the solid state and exhibit unusual electrical, photophysical, and magnetic properties. These complexes will be prepared using a series of new ligands that are specifically designed to bond to more than one metal and contain functional groups designed to support supramolecular structures. New host/guest chemistry based on assemblies formed by unique tripodal ligands such as 1,3,5-(CH3)3C6[CH2OCH2C(pz)3]3 (pz=pyrazolyl ring), and metal complexes of new bitopic ligands, such as Fe[C5H4CH(pz)2]2, that are based on the semi-flexible nature of the ferrocene core, will be targeted. Particularly important systems that will be investigated are spin-crossover Fe(II)N6 complexes, which are complexes with switchable domains, that open new possibilities for the development of novel memory devices. New types of multi-metallic coordination compounds will be synthesized that have highly organized structures in the solid state and exhibit unusual properties. This research will lead to the syntheses of new ligands that are specifically designed to bond to more than one metal and to develop the growing knowledge of the relationship between supramolecular structures and optical and magnetic properties. Such materials may have a significant potential impact by forming the basis for novel memory devices. This research is attractive for cultivating broadly trained specialists at various educational levels. Indeed, the PI has a tradition of diverse human resource and education development.
