Aromaticity in traditional cyclic systems is fundamentally dependent on a fully conjugated and co-planar pi-electron framework as defined by Hückel's rule.
The retrieved papers consistently confirm that standard aromaticity (such as Hückel aromaticity) relies on planar, fully conjugated cyclic pi-electron systems, with deviations like distortion or twisting leading to weakened aromaticity or nonaromatic states. No retrieved papers refute the premise that aromaticity requires these conditions for standard cyclic systems.
