Sweet 16: Copper(II) and zinc(II) benzofused porphyrin complexes with 16π-electron cores were prepared through two-electron oxidation of tetraphenyltetrabenzoporphyrin complexes with AgSbF6 (see scheme). Structural characterization and a variety of spectroscopic studies were carried out to analyze the electronic structure and study key trends in the antiaromatic properties of these novel 16π-electron porphyrin species.
