This CAREER award by the Inorganic, Bioinorganic and Organometallic Chemistry program supports research by Dr. Lisa Szczepura at Illinois State University on fundamental studies of hexanuclear octahedral molybdenum cluster complexes. The studies are aimed at probing two fundamentally important reactions of these complexes, ligand substitution and reduction-oxidation. An understanding the redox chemistry of the proposed aqua cluster complexes is likely to lead to the discovery of novel oxidants. In addition, the ability to predict substitution trends and generate linked hexanuclear cluster complexes together will enable the preparation of new solids based on the hexanuclear molybdenum unit with rigid spacer units which should provide room for molecules or ions to intercalate and deintercalate. Overall, these data are crucial to the future use of these cluster complexes in applications such as catalysis and materials chemistry. The educational component of this project involves the training and mentoring of women and underrepresented minorities. The PI proposes to run enrichment workshops that parallel the general chemistry sequence; these workshops will be available to students who are members of the Illinois Louis Stokes Alliance for Minority Participation (ILSAMP). Students from underrepresented groups will be recruited from these workshops as well as from other classes to conduct undergraduate research in the PI's laboratory. By providing financial support to graduate and undergraduate students, the PI hopes to provide an environment where learning and mentoring are at the forefront. Increasing the number of chemistry graduates from such underrepresented groups is crucial to increasing diversity in the field of chemistry and in generating a workforce that is capable of solving the complex scientific problems facing society.

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支持伊利诺伊州立大学的Lisa Szczepura博士对六核八面体钼簇合物基础研究的研究。这些研究旨在探索这些配合物的两个基本的重要反应：配体取代和还原-氧化。了解所提出的水簇合物的氧化还原化学可能会导致发现新的氧化剂。此外，预测取代趋势并共同生成连接的六核簇合物的能力将使基于具有刚性间隔单元的六核钼单元的新固体的制备成为可能，这将为分子或离子提供插入和脱嵌的空间。总体而言，这些数据对这些簇合物在催化和材料化学等应用中的未来应用至关重要。该项目的教育部分涉及对妇女和代表性不足的少数群体的培训和指导。国际学生联合会提议举办与一般化学顺序平行的丰富讲习班；这些讲习班将向伊利诺伊州路易斯·斯托克斯少数群体参与联盟(ILSAMP)的成员提供。来自代表性不足群体的学生将从这些讲习班和其他班级中招募，在PI的实验室进行本科生研究。通过为研究生和本科生提供经济支持，PI希望提供一个学习和指导处于领先地位的环境。增加来自这类代表性不足群体的化学毕业生的数量，对于增加化学领域的多样性和培养一支能够解决社会面临的复杂科学问题的劳动力至关重要。
