The polyaromatics are a group of polymers composed by polyaminonaphthalenes, polyaminoanthracenes and polynaphthoquinones that have aromatic systems with two or three rings. In this work, films of polyaminoanthracene (PAA) and 1,5 polydiaminonaphthalene (PDAN-1,5) have been electropolymerized on Pt electrodes in a single compartment cell with three electrodes. Fourier transform infra-red (FTIR) and Raman spectroscopies have been used to confirm that the PAA structure is similar to that of polyaniline (PAni). Electrochemical studies have shown that the PAA and the PDAN-1,5 present only one redox pair. However, the PAA did not show a good electrochemical stability, in contrast to PDAN-1,5. The micrographs showed homogeneous and compact films, with globular structure and for both polymers, although PAA showed cracks produced during drying with cold air flow.
