This award in the Chemical Synthesis (SYN) program in the Division of Chemistry supports a project by Professor Lisa F. Szczepura from Illinois State University to examine the chemistry of carbene ligands bonded to multi-metal systems (clusters), and enhancing involvement of underrepresented minorities in STEM disciplines at Illinois State. The proposed studies are critical to the future use of these clusters in applications such as catalysis. Professor Szczepura and students will develop new methods for these clusters containing stabilizing carbenes. In addition to developing new methods, there is an interest in determining the impact of these clusters in yielding novel light-emitting materials. In addition, Professor Szczepura will engage in training and mentoring undergraduate and graduate students, running a STEM fair for underrepresented minorities on campus, and administering a program aimed at improving the success rate of underrepresented students in the sciences.Synthetic methodologies will be developed for the preparation of hexanuclear rhenium selenide and molybdenum chloride clusters containing N-heterocyclic carbene (NHC) ligands. The impact the NHCs have on the physical properties and small molecule activation of these cluster cores will be of primary interest. This award will also allow for an exploration into the viability of isolating supraoctahedral clusters containingthe more reactive Fischer and Schrock carbenes. Since the clusters with molybdenum and rhenium cores typically display interesting photophysical properties, the proposed research will enable these clusters to be adapted for applications such as sensors and luminescent materials.

该奖项在化学划分的化学合成计划（SYN）计划中支持了伊利诺伊州立大学的Lisa F. Szczepura教授的一个项目，以研究与多金属系统（集群）键合的卡宾配体的化学，并增强了伊利诺伊州[伊利诺伊州干diblesprenting少数族裔的涉及少数族裔的涉及而增强。拟议的研究对于这些集群在催化等应用中的未来使用至关重要。 Szczepura教授和学生将为这些包含稳定碳纤维的簇开发新方法。 除了开发新方法外，还有兴趣确定这些簇在产生新型的发光材料中的影响。 此外，Szczepura教授将参加培训和指导本科生和研究生，为校园内代表性不足的少数群体举办STEM，并管理旨在提高科学少学生成功率的计划，以制定六核含量不足的方法。 N-杂环卡宾（NHC）配体。 NHC对物理特性的影响和这些簇核的小分子激活将引起主要兴趣。 该奖项还将允许探索隔离含有更具反应性的Fischer和Schrock Carbenes的上contahedral carusters的生存能力。由于具有钼和rhenium核的簇通常显示出有趣的光物理特性，因此拟议的研究将使这些簇适应传感器和发光材料等应用。
