Redox-core Dendrimers as Supramolecular Modulators of Electron Transfer

本项目探讨树枝状结构中电子转移速率的分子结构-性质关系。这些结构包含一个氧化还原活性核，其周围排列着树突结构。合理设计这种结构的修改将使使用表征电子转移的新技术成为可能。这样的变化，如亲水和亲金属表面将探索到这一目的。此外，还将研究树状核结构的变化作为内部立体力的函数，并阐明其对电子转移的影响。这些系统中电子转移的调制与分子电子器件和金属蛋白领域有关。通过这个奖项，有机和大分子化学项目支持北卡罗来纳州立大学克里斯托弗·b·戈尔曼教授的研究。戈尔曼教授探索了人造物质的特性，这些物质包括一个电活性的核心，周围是一个不同成分和厚度的外壳，最后覆盖一层具有特定性能的外壳，如导电性或水溶性。这种结构的电子特性很有趣，在电子学领域有潜在的应用，也类似于被称为酶的生物结构。

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.
