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.

这个奖项由无机，生物无机和有机化学计划支持教授维克多N。Nemykin的明尼苏达大学-杜卢斯设计和表征新的卟啉和四氮杂卟啉直接连接到氧化还原活性过渡金属中心。 沿着合成了一系列具有中位二茂铁或二茂二茂铁结构单元的卟啉，以及二茂铁结构单元与大环相连或稠合的四氮卟啉。 系统的调查将改变的性质的金属离子纳入卟啉环，附加的茂金属片段的数量和相互取向，的性质之间的连接器的Spanoenes和卟啉，和程度的Spanoenes的旋转自由。 所述系统可以展示出对于高密度分子信息存储系统有用的混合价态和电子迁移性质。 该项目专门设计的模块化特征特别适合将参与研究的本科研究人员。 研究工作也将加强MS。明尼苏达大学杜卢斯分校研究生课程。
