Electron Transfer Through Sigma-Bonds

在有机动力学项目的资助下，亚利桑那大学的Glass教授将对sigma键合系统的电子转移机制进行基本的理解。通过应变sigma键、碳-锡sigma键和非键p原子轨道进行有效电子转移的可行性将被探索。预测的sigma芳香性也将进行测试。一些独特的化合物将被合成来证明所提出的概念。了解电子如何沿着烃链传递对材料和生物过程都很重要。这些结果可能为设计以sigma轨道和非键sigma体系为导电基础的导电材料提供新的基础，而不是通过pi轨道建立的导电基础。该项目将提供验证理论模型所需的实验结果。

With funding from the Organic Dynamics Program, Professor Glass of the University of Arizona will develop a fundamental understanding of the mechanism of electron transfer through sigma bonded systems. Feasibility of efficient electron-transfer through strained sigma-bonds, carbon-tin sigma bonds, and nonbonding p-atomic orbitals aligned for sigma type overlap will be explored. Prediction of sigma aromaticity will also be tested. A number of unique compounds will be synthesized to demonstrate the concepts proposed. Understanding how electrons are transported along hydrocarbon chains is important to both materials and biological processes. These results may provide a novel basis for designing electrically conducting materials in which sigma orbitals and nonbonding sigma systems are the basis for conduction rather than the well-established conduction through pi-orbitals. This project will provide experimental results which are needed to substantiate theoretical models.
