The hemiporphyrazine variants hydroxybenziphthalocyanine and dihydroxybenziphthalocyanine can be generated via sequential Schiff base condensation reactions by using bis(diiminoisoindoline) benzene intermediates. These compounds are not aromatic due to the lack of conjugation across the benzene rings, yet these macrocycles exhibit striking absorption bands in the low energy region of the UV-visible spectrum.

The syntheses and structural elucidations of three different cobalt complexes of m-benziphthalocyanine are reported; both Co(II) and Co(III) complexes can be generated, and the ring undergoes partial oxidation upon metalation with Co(OAc)2·4H2O.

Zinc can be inserted into the carbahemiporphyrazines by use of the organometallic reagent diethylzinc; in the case of benziphthalocyanine, concomitant alkylation of an α-carbon position and metalation occurs.
