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

该奖项由无机、生物无机和有机金属化学项目颁发，支持明尼苏达大学德卢斯分校Viktor N. Nemykin教授设计和表征与氧化还原活性过渡金属中心直接相连的新型卟啉和四氮卟啉。以中二茂铁或鲁二茂铁为单位的卟啉与以二茂铁为单位的四氮卟啉在大环上连接或熔合而成。系统的研究将改变纳入卟啉环的金属离子的性质，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。该系统可能表现出对高密度分子信息存储系统有用的混合价和电子迁移特性。该项目特别设计，模块化的特点特别适合将参与研究的本科生研究人员。这项研究工作也将加强明尼苏达大学德卢斯分校的硕士研究生项目。

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.
