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

这个无机、生物无机和有机金属化学项目的奖项支持南卡罗来纳大学的Daniel Reger教授设计新型的多金属配位化合物，这些化合物在固态中具有高度有组织的结构，并表现出不同寻常的电学、光物理和磁性。这些配合物将使用一系列新的配体来制备，这些配体专门设计用于与一种以上的金属结合，并包含用于支持超分子结构的官能团。新的主客体化学基于独特的三脚配体如1,3,5-(CH3)3C6[CH2OCH2C(pz)3]3 （pz=吡唑环）形成的组装，以及新的双位配体的金属配合物，如Fe[C5H4CH(pz)2]2，基于二茂铁核的半柔性性质，将成为目标。将研究的特别重要的系统是自旋交叉Fe(II)N6配合物，这是具有可切换结构域的配合物，为开发新型存储器件开辟了新的可能性。新型的多金属配位化合物在固体状态下具有高度组织化的结构和不同寻常的性能。这项研究将导致新配体的合成，这些配体专门设计用于与多种金属结合，并发展超分子结构与光学和磁性之间关系的日益增长的知识。这种材料可能通过形成新型存储设备的基础而具有重要的潜在影响。这项研究对培养各种教育水平的受过广泛训练的专家具有吸引力。事实上，PI具有多元化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.
