CAREER: Construction of Magnetic Cyanide-, Acetylide-, and Butadiynylide-Based Clusters

这项由无机化学、生物无机化学和金属有机化学项目颁发的职业奖项支持肯塔基大学的斯蒂芬·M·霍姆斯教授研究表现出可调磁性和光磁性行为的分子材料。制备了一系列稳定的、磁各向异性的聚吡唑基硼酸酯、氰基金属酸酯和炔基前驱体，并可控地聚集成一系列磁性和光磁性多核簇合物。基本的结构-性质关系有助于理解和设计可调的磁性和光学性质，特别是在基于分子的存储器件中的应用。面向本科生、研究生和博士后的暑期纳米学院和物理性质测量课程从第一原理的角度介绍和描述纳米科学和光谱学的概念。讨论了用户提供的材料的光谱和磁特性，并由学生使用远程访问进行教程实验。新获得的技能和获得仪器的机会使各种区域本科机构的研究小组能够及时和具有成本效益地收集和解释光谱数据。中心学院和肯塔基州立大学(当地少数族裔服务和历史悠久的黑人学院和大学(HBCU)机构)区域导师的合作参与及其学生的交流和支持扩大了整个区域的纳米课程开发和研究活动。

This CAREER award by the Inorganic, Bioinorganic and Organometallic Chemistry Program supports work by Professor Stephen M. Holmes at the University of Kentucky to study molecule-based materials that exhibit tunable magnetic and photomagnetic behaviors. A series of stable and magnetically anisotropic poly(pyrazolyl)borate cyanometalate and alkynyl precursors are prepared and controllably aggregated into a series of magnetic and photomagnetic polynuclear cluster derivatives. The fundamental structure-property relationships assist in the understanding and engineering of tunable magnetic and optical properties, especially for applications in molecule-based memory devices. The Summer Nanoscale Institute and physical property measurement courses for undergraduate, graduate and postdoctoral students introduce and describe nanoscale science and spectroscopy concepts from a first-principle standpoint. Spectroscopic and magnetic characterizations of user-supplied materials are discussed and tutorial experiments are performed by students using remote access. The newly acquired skills and access to instrumentation enable the timely and cost-effective collection and interpretation of spectroscopic data for research groups at a variety of regional undergraduate institutions. Collaborative participation of regional mentors and the exchange and support of their students at Centre College and Kentucky State University (local minority-serving and Historically Black Colleges and University (HBCU) institutions) expand nanoscale curriculum development and research activities across the region.
