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

该职业奖由无机、生物无机和有机金属化学项目颁发，支持肯塔基大学Stephen M. Holmes教授对具有可调磁性和光磁性行为的分子基材料的研究。制备了一系列稳定且磁性各向异性的聚吡唑基硼酸盐、氰金属酸盐和炔基前驱体，并可控地聚集成一系列磁性和光磁性多核团簇衍生物。基本的结构-性质关系有助于理解和工程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、研究生和博士后的夏季纳米尺度研究所和物理性质测量课程，从第一性原理的角度介绍和描述纳米尺度科学和光谱学概念。讨论了用户提供材料的光谱和磁性表征，并由学生使用远程访问进行了教学实验。新获得的技能和获得仪器的途径使各种区域本科院校的研究小组能够及时和经济有效地收集和解释光谱数据。在中心学院和肯塔基州立大学（当地少数民族服务和历史上的黑人学院和大学（HBCU）机构），区域导师的合作参与和学生的交流和支持扩大了整个地区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.
