Tetrapyrrolic-based molecules and polymers are very important compounds due to their fundamental roles as light absorbers and redox centres in biologic systems and also because of their numerous applications in practical devices.1 Most of these applications are based in both, the redox and light-absorbing properties of porphyrins and phthalocyanines2, and in their capacity of to convert the light energy into an electrochemical potential.3 In several cases, the incorporation of tetrapyrrolic centres into conducting polymers is very convenient for device fabrication and application, because it confers an additional stability to the organic system and also could improve the diffusion and migration of the electrical or photo-generated charge carriers to and from a base contact electrode.4
