Aconvenient and high yield synthetic route to arylene derivatives was reported and their electrochemical character was shown by properties of polymer with alternate arylene and bispyridine, bisthiophene, bisfurane and bisthiazole units. Polymerization is processed as two steps bielectronic oxidation of molecules. In monoelectronic oxidation stable radical cation is formed with spin located on phenothiazine. The electrochemical properties of polymer are dependent on film thickness deposited on electrode. In the case of the thin layers one can observe characteristic redox couple of phenothiazine oxidation to radical cation. Analysis of polymer behaviour and results of spectrochemical measurements point on mixed type of electroconducting.
