Promising as a chelating agent and as a photosensitizer hemiporphycene is the third porphyrin isomer after porphycene and corrphycene with a central N 4 coordination sphere. The stable octaethyl derivative of hemiporphycene 1 was obtained by the combination of a McMurry reaction a reductive CC cleavage from a bis(tetraphyrroledialdehyde). Like its congeners. 1 possesses a planar ring skeleton.
