Lanthanide-Containing Cluster Complexes - Chemistry and Materials

在这个由化学系化学合成计划资助的项目中，亚利桑那大学化学和生物化学系郑志平教授将系统地探索合成具有结构兴趣和实际意义的稀土簇合物。研究将使用氨基酸和氨基酸类配体、官能化的羧酸盐和β-二酮酸盐来控制稀土离子的水解和高核度簇合物的组装。将研究阴离子在这类物种组装中的模板作用。功能化的β-二酮盐将被用于制备簇合物，这些簇合物在生物医学成像、发光液晶显示器、磁光数据存储和磁制冷技术中具有潜在的应用价值。这项工作将导致迫切需要的合成方法，从根本上有趣的，但否则合成难以捉摸的稀土化合物。具有重大技术应用的含镧材料的发现是可望的。这项研究将为学生的教育和培训提供充足的机会，从本科预科到研究生，包括那些在科学界历史上代表性不足的学生。

In this project funded by the Chemical Synthesis Program of the Chemistry Division, Professor Zhiping Zheng of the Department of Chemistry and Biochemistry at University of Arizona will systematically explore the synthesis of structurally interesting and practically significant lanthanide cluster complexes. Studies will be carried out using amino acids and amino acid-like ligands, functionalized carboxylates, and beta-diketonates to control the hydrolysis of the lanthanide ions and the assembly of high-nuclearity clusters. The templating effects of anions in the assembly of such species will be investigated. Functionalized beta-diketonates will be used for the making of cluster complexes that are potentially useful in biomedical imaging, luminescent liquid-crystal displays, magneto-optical data storage, and magnetic refrigeration technology. This work will lead to much needed synthetic approaches to fundamentally interesting but otherwise synthetically elusive lanthanide compounds. Discovery of lanthanide-containing materials with significant technological applications is anticipated. The research will provide ample opportunities for the education and training of students, from pre-undergraduate to graduate, including those from groups that are historically underrepresented in the sciences.
