Mobius Antiaromatic Bisphosphorus Complexes of [30]Hexaphyrins

摘要

Aromaticity is a fundamental concept in organic chemistry and is important in understanding, for instance, that the energetic stability of benzene originates from cyclic π-electron derealization. The Huckel rule is very useful, and helps us to predict that cyclic [4n+2]π-and [4n]π-conjugated systems should be aromatic and antiaromatic, respectively, given that their π systems lie on two-sided normal planes.
