The application of pyrrole-substituted porphyrin electropolymers for simultaneous optical and electrochemical analysis of red-ox active analytes, namely diazo-conjugated dyes of Sudan family, is presented. Sudan colorants are widely used in many fields, but accurate screening of their consumption is required due to their high toxicity. The inherent electrochemical activity of Sudan dyes, as far as their intense coloration, makes possible to find the appropriate conditions of hybrid optical and electrochemical porphyrin electropolymer based sensor array system application. This approach allowed a significant increase in the chemical information, improving the analytical system performance in terms of selectivity and sensitivity, and permitted the fast and simple monitoring of Sudan dye analytes.
