Femtosecond charge transfer (CT) dynamics in a series of self-assembled monolayers with an oligo(phenylenethynylene) and oligo(phenyl) backbone is addressed by resonant Auger spectroscopy using the core hole clock method. The characteristic CT times are found to depend strongly on the character of the molecular orbital (MO) which mediates the CT process. This demonstrates that the efficiency and rate of CT through molecular frameworks can be controlled by resonant injection of the charge carriers into specific MOs.
采用核心能级钟法的共振俄歇谱学研究了一系列带有聚（苯乙炔）和聚（苯）主链的自组装单层中的飞秒荷移（CT）动力学。发现特征 CT 时间强烈依赖于介导 CT 过程的分子轨道（MO）的性质。这表明可以通过将电荷载流子共振注入特定的 MO 来控制通过分子框架的 CT 的效率和速率。
