Abstract

Three linear dimers with two redox-active planarized triphenylamines were synthesized and their structures verified by X-ray crystallography. Their radical cations, which exhibit electron self-exchange between the two redox centers, are of great interest. This process was thoroughly investigated by means of electron paramagnetic resonance spectroscopy, absorption spectroscopy, and (time-dependent) density functional theory calculations. A comparison of the key parameters of electron transfer with non-planarized nitrogen-centered building blocks emphasizes the impact of using redox centers with low internal reorganization energies. However, the distance-dependence attenuation factor of the super-exchange mechanisms remains similar.

摘要

合成了三种含有两个氧化还原活性平面化三苯胺的线性二聚体，并通过X射线晶体学对其结构进行了验证。它们的自由基阳离子在两个氧化还原中心之间表现出电子自交换，这引起了人们的极大兴趣。通过电子顺磁共振光谱、吸收光谱和（含时）密度泛函理论计算对这一过程进行了深入研究。将这些具有平面化结构的氧化还原中心与非平面化的氮中心结构单元的电子转移关键参数进行比较，强调了使用具有低内部重组能的氧化还原中心的影响。然而，超交换机制的距离依赖性衰减因子仍然相似。
