With the support of the Chemical Synthesis program in the Division of Chemistry, Professor Lisa Szczepura of Illinois State University will develop synthetic methodologies for the preparation and study of transition metal cluster complexes containing acetylide-based ligands. The chemistry of the related monometallic transition metal species containing acetylide ligands is quite rich in terms of their structures, reactivity and physical properties making them desirable as precursors in the preparation of reactive catalysts and building blocks in the preparation of extended materials. This project focuses on the synthesis and properties of the related but relatively unexplored multimetallic cluster systems containing acetylides. The potential of the newly synthesized clusters in catalysis applications and in the preparation of hybrid materials will be assessed. This research will be conducted in collaboration with undergraduate and master’s level students. In addition, Dr. Szczepura will work with units across campus to engage with underrepresented students in science with the goal of involving them in the proposed studies. Under this award, Dr. Szczepura and her team at Illinois State University will explore fundamental aspects of rhenium-based cluster-acetylide chemistry to determine how the unique properties of these cluster cores impact the chemistry of the coordinated acetylide ligands. The main objectives of this proposal include an exploration into the chemistry of Re-based acetylides to determine the nature of these cluster-carbon interactions, the development of synthetic methodologies which link cluster cores together via C-based bridges, and investigations into the electrochemical and photophysical properties of these organometallic cluster complexes. Results from this work have the potential to provide a deeper understanding of the nature of Re-based cluster-carbon interactions. The results obtained from the proposed objectives will advance the fundamental understanding of organometallic hexanuclear octahedral clusters while exploring a new facet of metal acetylide chemistry.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

在化学合成计划中的支持下，伊利诺伊州立大学的Lisa Szczepura教授将开发合成方法，用于制备和研究含有基于乙酰基的配体的过渡金属簇复合物。相关的单金属过渡金属物种的化学性质在其结构，反应性和物理特性方面非常丰富，使其成为准备性催化剂和构建块的预兆，以作为准备扩展材料制备的前体。该项目侧重于相关但相对意外的含有乙酰基的多金属群集系统的综合和特性。新合成的簇在催化应用中的潜力以及在混合材料的制备中的潜力将得到评估。这项研究将与本科和硕士级学生合作进行。此外，Szczepura博士将与校园各个部门合作，与代表性不足的科学学生互动，目的是让他们参与拟议的研究。根据该奖项，Szczepura博士和她在伊利诺伊州立大学的团队将探讨基于Rhenium的簇 - 乙酰化化学的基本方面，以确定这些集群核心的独特性能如何影响协调的乙酰基体配体的化学反应。该提案的主要目标包括对基于RE的乙酰基化学的探索，以确定这些簇 - 碳相互作用的性质，合成方法的开发，这些方法通过基于C的桥将簇核心连接在一起，并研究了这些有机群集复合物的电化学和光生理特性。这项工作的结果有潜力可以更深入地了解基于RE的簇 - 碳相互作用的性质。从提出的目标获得的结果将提高对有机六核八面体簇的基本理解，同时探索金属乙酰基化学的新方面。该奖项反映了NSF的法定任务，并被认为是通过基金会的知识分子优点和更广泛的影响审查标准来通过评估来通过评估来支持的。
