heptaphyrin with Möbius aromatic character is reported. The 1H NMR data indicated a weak Möbius aromaticity at 298 K; however, at 213–183 K, the molecule predominates [4n]π Möbius conformation with strong diatropic ring current, which was further confirmed by X‐ray analysis. The protonation experiment led to preservation of the Möbius aromaticity at 298 K. Nevertheless, the experimental results were further
报道了一种新的融合熔融修饰的具有莫比乌斯(Möbius)芳香特性的32π七
卟啉。的1个H NMR数据指示在298K弱莫比乌斯芳香性; 但是,在213–183 K时,该分子以[4 n ]πMöbius构象为主,并具有强的变径环电流,这通过X射线分析得到了进一步证实。质子化实验导致298 K时保持了莫比乌斯(Möbius)芳香性。然而,实验结果得到了理论研究的进一步支持。总的来说,这项研究代表了莫比乌斯芳香族稠合核修饰膨胀
卟啉的第一个例子。
