Möbius aromaticity
A concept in organic chemistry where a cyclic molecule with a Möbius-like π-electron arrangement exhibits aromatic stability, following the 4n rule instead of Hückel's 4n+2 rule.
Möbius aromaticity is observed in cyclic molecules with a topology like a Möbius strip.
General term for aromaticity; メビウス芳香族性 specifies the Möbius topology variant.
Hückel's rule (4n+2) applies to planar aromatic systems, while Möbius aromaticity follows the 4n rule.
From the German mathematician August Ferdinand Möbius, whose Möbius strip topology inspired the concept in chemistry.
