  • A new fused core-modified 32p heptaphyrin with Mçbius aromatic character is reported. The H NMR data indicated a weak Mçbius aromaticity at 298 K; however, at 213–183 K, the molecule predominates [4n]p Mçbius conformation with strong diatropic ring current, which was further confirmed by X-ray analysis. The protonation experiment led to preservation of the Mçbius aromaticity at 298 K. Nevertheless, the experimental results were further supported by theoretical studies. Overall, this study… CONTINUE READING
