While benzene has an ideal small ring-diameter, the current-induced magnetic field is limited by two-way ring currents in the para-and ortholinked case, and low current in the meta-linked case. Benzene is an annulene, but is a special case being a highly symmetric aromatic molecule. Tsuji et al. demonstrated that in annulenes with bond-length alternation, the current may predominantly flow the long way around the ring-structure if the injection-point into the short way in the ring is via a long (formally single) bond. In ortho-connected benzene-like molecules, it may therefore be possible to avoid the current running the short way as it does in benzene (Figure ).
