Electropolymerizable iron (III) and cobalt (II) dicyanophenoxy tetraphenylporphyrin complexes: Potential electrocatalysts

Two novel asymmetric dicyanophenoxy-derivatised iron (III) and Co(II) porphyrin complexes have easily been electropolymerised onto glassy carbon electrodes. The thin solid films exhibited excellent stability and electrocatalysis towards the direct detection of important analytes such as nitrite, nitric oxide, and hydrogen peroxide in aqueous solutions.
