The electronic coupling between two amine redox sites bridged through the 5,5′‐positions of the [Re(CO)3Cl]‐chelated 2,2′‐bipyridine was studied by the electrochemical, spectroscopic, and EPR analysis. Interestingly, multiple near‐infrared bands were observed in this new organic mixed‐valent system. The results are interpreted with the aid of DFT and TDDFT calculations.
通过电化学,光谱和EPR分析研究了通过[Re(CO)3 Cl]螯合的2,2'-联吡啶的5,5'-位置桥接的两个胺氧化还原位点之间的电子偶联。有趣的是,在这个新的有机混合价系统中观察到了多个近红外谱带。借助DFT和TDDFT计算来解释结果。
