Rezumat:

Several meta and para mono and bis (azulen-1-ylazo) or phenylazo substituted phenylene derivatives, 1-4 were electrochemically characterized using DPV and CV methods. All the compounds presented several oxidation and reduction potentials. These values are correlated with HOMO and LUMO energies; a very good fit for oxidations and an acceptable link for reductions were observed. The influence of the arylazo groups on the potentials is discussed in comparison with that of the alkyl groups. Using cyclations in anodic field, films are obtained for the azulenic compounds with the unoccupied 3 position.
