Hückel-like rule of superaromaticity for charged paracyclophanes

Hückel-like rule of superaromaticity for charged paracyclophanes. Aihara, J. Chemical Physics Letters, 381(1–2):147–153, 2003. ISBN: 0009-2614

Paper doi abstract bibtex

Paracyclophanes, in which four or more benzene units are linked at the 1,4-positions by ethylene bridges, show annulene characteristics upon charging. It was proved that a Hückel-like rule of superaromaticity holds for molecular ions of these species. Here superaromaticity represents energetic stabilization due to cyclic motion of ��-electrons along the macrocycle. If this type of paracyclophane molecule or any of its closed-shell molecular ions is super-antiaromatic, it will probably become superaromatic either by acquiring two more π-electrons or by losing two π-electrons.
