RUI - Preparation, Characterization, and Theoretical Modeling of Organometallic Porphyrins and Tetraazaporphyrins

在这个由化学系化学合成计划资助的项目中，明尼苏达大学德卢斯分校(UMD)化学和生物化学系的Nemykin教授将探索制备有机金属卟啉及其芳香族大环类似物的合成途径。虽然简单的金属有机化合物(即二茂铁)的化学已经得到了很好的探索，但在有机金属芳香族大环的开发方面却进展甚微。Nemykin博士和其他人最近发现，将有机金属取代基引入到卟啉核心中会导致罕见的长程金属-金属耦合性质，这对于此类化合物在分子电子学、随机存取存储器件和近红外光学限制器组件中的应用至关重要。将使用电化学、光谱电化学和化学氧化方法来鉴定目标化合物的性质。这项工作可能导致制备用于分子电子学和氧化还原驱动传感器的高效模块。该方法的成功发展将对任何需要合成分子的领域产生影响，例如微电子、环境工程以及生物和化学研究活动。此外，该项目还将为本科生和研究生提供培训机会。学生，以及博士后研究员，将教学和进行研究，为在一个以本科为主的机构的职业生涯做准备。

In this project funded by the Chemical Synthesis Program of the Chemistry Division, Professor Nemykin of the Department of Chemistry and Biochemistry at University of Minnesota Duluth (UMD) will explore synthetic pathways for the preparation of organometallic porphyrins and their aromatic macrocyclic analogues. While chemistry of simple organometallic compounds (i.e. ferrocenes) is well-explored, little progress has been made in the development of organometallic aromatic macrocycles. Dr. Nemykin and others have recently shown that introduction of organometallic substituents into the porphyrin core results in rare long-range metal-metal coupling properties, which are essential for the application of such compounds in molecular electronics, random access memory devices and components for near infra-red optical limiters. Electrochemical, spectroelectrochemical, and chemical oxidation methods will be used to identify the properties of the target compounds. This work could result in the preparation of efficient modules for molecular electronics and redox-driven sensors. Successful development of the methodology will have an impact on any area in which the synthesis of molecules is needed, such as microelectronics, environmental engineering, as well as biological and chemical research activities. In addition, this project will provide training opportunities for undergraduate and graduate (M.S.) students, as well as for a post-doctoral researcher who will be both teaching and conducting research in preparation for a career at a predominantly undergraduate institution.
