The term aromaticity was initially introduced to describe the properties of molecules with special aromatic odor, such as benzene, and now is considered as one of the most important concepts in ...

"This is the first time that a ring consisting of six nitrogen atoms has been synthesized that follows the Hückel rule for aromaticity. Its aromatic character is further supported by bond-length ...

Aromaticity describes a class of cyclic, conjugated molecules that exhibit enhanced thermodynamic stability and a characteristic response to magnetic fields. In systems following Hückel’s rule, a ...

Excited-state aromaticity refers to the transient stabilisation or destabilisation of cyclic π-electron systems upon photoexcitation. In the electronic ground state many organic compounds obey ...
