Uses

Used in Microbial Fuel Cell Applications:
Mg(II) Porphine is used as a component in the preparation of metalloporphyrin-doped anti-fouling cathode membranes. These membranes are crucial for enhancing the performance of microbial fuel cells, which are used for wastewater treatment. The incorporation of Mg(II) Porphine into the cathode membrane helps to improve the efficiency of the microbial fuel cell by reducing fouling and increasing the overall performance of the system.

Crystallographic, spectroscopic and electrochemical characterization of pyridine adducts of magnesium(II) and zinc(II) porphine complexes

A new purification method of magnesium(II) and zinc(II) porphine complexes (MgP and ZnP, respectively) by crystallization of their respective pyridine adducts is described. Pure MgP and ZnP can be regenerated by removal of the coordinated pyridine ligands by heating at 200 C under vacuum. X-ray crystallographic structures of the pyridine adducts are presented for the first time. NMR analyses of the adducts reveal the coordination of two pyridine molecules. Electrochemical as well as UV-vis absorption spectroscopy analyses in DMF of MgP·(Py)2, ZnP·(Py)2, MgP and ZnP indicate that pyridine adducts are totally dissociated. Besides, oxidation peaks of these complexes are totally irreversible, revealing a high reactivity of the oxidized species. Electrolyses at the first oxidation potential lead to the formation of the meso-meso (ZnP)2 and (MgP)2 dimers, oligomers and polymers on the electrode surface, as attested by MALDI-TOF mass spectrometry and UV-vis absorption spectroscopy analyses of the crude solution.

METHOD OF MAKING PORPHYRINS

A method of making a compound of Formula I: is carried out by condensing a pair of compounds of Formula II (which pair may be the same or different), or by condensing a compound of Formula III with a compound Formula IV, to produce a compound of Formula I. The condensing step may be carried out with a metal salt under basic conditions.
