This project explores molecular structure-property relationships of electron transfer rates in dendritic structures. These structures encompass a redox-active core around which is arrayed a dendritic structure. Rationally designed modifications of this structure will make possible the use of new techniques for characterizing electron transfer. Such variations as a hydrophilic and metallaphilic surfaces will be explored to this end. In addition, changes in the structure of the dendritic core as a function of internal steric forces will be investigated and its effect on electron transfer elucidated. Modulation of electron transfer in these systems has relevance to the areas of molecular electronic devices and metallaproteins.With this Award, the Organic and Macromolecular Chemistry Program supports the research of Professor Christopher B. Gorman of North Carolina State University. Professor Gorman explores the properties of man-made substances that incorporate an electrically active core surrounded by a shell of varying composition and thickness, finally covered by a skin having specific properties such as electrical conductivity or water solubility. The electronic properties of such structures is of interest and has potential applications in the area of electronics as well as being analogous to biological structures called enzymes.

本计画探讨树枝状结构中电子转移速率的分子结构-性质关系。 这些结构包括氧化还原活性核心，围绕该核心排列有树枝状结构。 这种结构的合理设计的修改将有可能使用新的技术来表征电子转移。 为此，将探索亲水性和亲金属性表面等变化。 此外，作为内部空间力的函数的树枝状核心的结构的变化将进行调查，并阐明其对电子转移的影响。 这些系统中电子转移的调节与分子电子器件和金属蛋白质领域有关。有了这个奖项，有机和大分子化学计划支持Christopher B教授的研究。来自北卡罗来纳州州立大学的戈尔曼。 戈尔曼教授探讨了人造物质的特性，这些物质包含由不同成分和厚度的外壳包围的电活性核心，最后由具有特定特性的皮肤覆盖，如导电性或水溶性。 这种结构的电子性质是令人感兴趣的，并且在电子学领域以及类似于称为酶的生物结构中具有潜在的应用。
