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.

在有机动力学项目的资助下，亚利桑那大学的格拉斯教授将对通过西格玛键合系统进行电子转移的机制有一个基本的了解。 将探讨通过应变西格玛键、碳-锡西格玛键和西格玛型重叠排列的非键合 p 原子轨道进行有效电子转移的可行性。 还将测试西格玛芳香度的预测。 将合成许多独特的化合物来证明所提出的概念。 了解电子如何沿着碳氢链传输对于材料和生物过程都很重要。 这些结果可能为设计导电材料提供新的基础，其中西格玛轨道和非键合西格玛系统是传导的基础，而不是通过π轨道进行良好的传导。 该项目将提供证实理论模型所需的实验结果。
