摘要: [6.8]3Cyclacene is an interesting belt-like structure displaying aromatic–non-aromatic alternation, which useful to gain understanding of the intramolecular and intermolecular interactions between anisotropic cones in magnetic behavior such rings. From analysis certain components induced field 13C-NMR shielding under its own principal axis system (PAS), individual overall each respective aromatic non-aromatic fragments can be clearly described. Interestingly, response [6.8]3cyclacene suggests a characteristic given by confinement into structure.
