New asymmetric porphyrins, with electroactive functionalities were synthesized. 5,15 Bis[4 N,N diphenylamino phenyl] 10,20 bis[3 N ethylcarbazoyl ]porphyrin and its Zn II derivative allow the electrochemical formation of conjugated, conducting and stable polymeric films over semitransparent indium tin oxide surface. The spectral changes observed upon oxidation of the films produced different colorations. The polymeric materials showed the generation of photoinduced charge separation states and charge migration upon porphyrin excitation, making them promising candidates for application in optoelectronics device
