Iron porphyrin polymer films: Materials for the modification of electrode surfaces and the detection of nitric oxide
Abstract
We are currently investigating a new method for the detection and quantification of nitric oxide (NO) based on a carbon electrode chemically modified with an iron porphyrin polymer film. Commercially available vinyl-substituted iron porphyrin monomers can be polymerized directly onto electrode surfaces through a published electrochemical polymerization process. We are also developing a synthesis for a new vinyl-substituted monomer, iron 5,10,15-triphenyl-20-vinyl porphyrin chloride, in hopes of improving polymer film stability. The electrochemistry of NO is also being investigated at electrodes chemically modified with an iron porphyrin polymer film. We are studying the catalytic oxidation of iron porphyrin bound NO to nitrate by molecular oxygen. The reaction with molecular oxygen is preceded by a one electron reduction of the iron porphyrin-NO complex. If currents proportional to nitric oxide concentration can be measured, a new NO electrochemical sensor will be designed.
