Comparative Study between Two Polymers of Arylene-Vinylene Units: Electrochemical, Spectroscopic Characterization and Resistivity Measurements

Abstract:

Two arylenevinylenes compounds formed with thienyl or furyl units substituted by a cyano group at the ethylene linkage were studied by direct anodic oxidation in CH2Cl2/Bu4NBF4 0,2M medium on platinum electrode using cyclic voltammetry method. By applying a sequential linear potential scan rate of 100 mV.s-1 between 0-1,6 V versus Ag /Ag+ (0,1 M) / CH2Cl2, these two organic compounds could be polymerized. The electrosynthetized conducting polymers were also prepared by potentiostatic method then characterized by IR and UV spectroscopies and their conductivity was evaluated.
