Giant, 162 π-electron aromatic ring shows that we haven’t reached the upper limit of Hückel’s rule yet
Hückel’s rule, developed to explain the properties of the six aromatic electrons in benzene, is still valid for a giant aromatic ring with 162 π electrons that is many times the size of the simplest aromatic.
