Substituting two carbon atoms in benzene with a nitrogen and a boron creates a structurally analogous isoelectronic molecule. Indeed, such heterobenzenes like 1,2-azaborine (Figure ) has significant bond-length alternation. Consequently, the double bonds are localized and we can connect the linkers and electrodes in such a way that the current through the short way around the ring is reduced. Still, in the case of the ortho-connected azaborine, the current density through the short path of the ring is too strong, and the total current is lower than ortho-linked benzene, which is also an unfortunate consequence of increased bond-length alternation. Consequently, the magnetic field is slightly lower than that of the ortho-linked benzene.
