Cover Feature: Quest for the Most Aromatic Pathway in Charged Expanded Porphyrins (Chem. Eur. J. 6/2023)

The aromaticity of charged expanded porphyrins turns out to be much more complex study than that their planar neutral analogues. In particular, identifying the most conjugated circuit is no longer straightforward. addition planarity, protonation and deprotonation porphyrinoids play an important role in determining aromaticity. We have demonstrated largest do not present a clear main conjugation pathway. Among preferred aromatic indices, AVmin ends up being useful tool for recognizing path. can relate difficulty finding path porphyrin number pieces puzzle. Thus, state [36]octaphyrin represented as puzzle with few pieces; protonated deprotonated states are presented puzzles indicate they difficult complete. More information found Research Article by M.
