RUI - Preparation, Characterization, and Theoretical Modeling of the Mixed-Valence States in Polynuclear Porphyrins and Tetraazaporphyrins

这项由无机化学、生物无机化学和金属有机化学计划颁发的奖项支持明尼苏达大学德卢斯分校的Viktor N.Nemykin教授设计和表征直接与氧化还原活性过渡金属中心相连的新的卟啉和四氮杂卟啉。合成了一系列含中二茂铁或均三茂铁单元的卟啉，以及连接或熔合到大环上的二茂铁单元的四氮杂卟啉。系统的研究将改变引入到卟啉环上的金属离子的性质，附加的茂金属碎片的数量和相互取向，茂金属和卟啉之间的连接物的性质，以及茂金属的旋转自由程度。这些体系可能表现出混合价和电子迁移性质，这对高密度分子信息存储系统是有用的。该项目的专门设计、模块化特点特别适合将参与研究的本科生研究人员。这些研究工作还将加强明尼苏达大学德卢斯分校的理工科硕士研究生课程。

This award by the Inorganic, Bioinorganic and Organometallic Chemistry Program supports the work of Professor Viktor N. Nemykin of the University of Minnesota - Duluth to design and characterize new porphyrins and tetraazaporphyrins directly connected to redox-active transition metal centers. A series of porphyrins with meso-ferrocene or ruthenocene units will be synthesized along with tetraazporphyrins with ferrocene units connected or fused to the macrocycle. Systematic investigations will vary the nature of the metal ions incorporated into the porphyrin ring, the number and mutual orientations of the appended metallocene fragments, the nature of the linkers between the metallocenes and porphyrins, and the extent of rotational freedom of the metallocenes. The systems may demonstrate mixed valence and electron migration properties that are useful for high-density molecular information storage systems. The specifically designed, modular character of the project is especially suitable for the undergraduate researchers who will take part in the research. The research efforts will also strengthen the M.S. Graduate Program at the University of Minnesota - Duluth.
