Pyrrolic Pyrrole brominated porphyrins, water

Synthesis of Water-Soluble / -Pyrrole Brominated Porphyrins... 

The electrochemical behavior of water-soluble yS-pyrrole brominated porphyrins is more complex than that of their water insoluble analogs. The metal-centered redox reactions of (TMPyP)Mn and (TMPyPBrg)Mn are reversible while the majority of porphyrin ring-centered redox reactions of the free-base, Cu, and Mn derivatives of TMPyPBrs are irreversible The metal-centered oxidation of (TMPyPBr8)Mn is anodically shifted by 420 mV compared to 1/2 for the corresponding reaction of (TMPyP)Mn (Table 9.2). The metal-centered...
