Advances in Chemical Engineering and Science Vol.2 No.3，July 11, 2012 Metal complexes derived from porphyrins, often called metalloporphyins, occur naturally. One of the best-known families of porphyrin complexes is heme, the pigment in red blood cells, a cofactor of the protein hemoglobin. Porphin is the simplest porphyrin, a rare compound of theoretical interest. Meer weergeven Porphyrins are a group of heterocyclic macrocycle organic compounds, composed of four modified pyrrole subunits interconnected at their α carbon atoms via methine bridges (=CH−).
