Stable antiaromatic expanded porphyrins were designed by the judicious implementation of meso-imidazolyl groups, which cause stabilization through the creation of a hydrogen-bonding network (see structures) that overcomes antiaromatic electronic destabilization. Both the [28]hexaphyrin 1 and the [36]octaphyrin 2, which contain imidazolyl groups at two opposite meso positions, are shown to be stable Hückel antiaromatic species.
