Electrochemical synthesis and characterisation of conducting polypyridazine

Abstract

Conducting polypyridazine with elec. conductivity of about 1S/cm was synthesized by electrochem. method. Cyclic voltammetry studies on pyridazine polymerisation and on the polymer film were carried out. The doping level of the as-grown polypyridazine with anion ClO4- was about 25%. In the FTIR spectra of polypyridazine, four absorption bands at 1330, 1120, 1100 and 840 cm-1 induced by 3, 6-disubstituted pyridazine structure were observed The doped polymer film has three optical absorption peaks at 0.9, 1.8, 3.4 eV, resp., and this indicates the evolution of bipolaron state in doped polypyridazine.
