Investigations of electrochemical and spectroelectrochemical properties (UV-Vis, EPR) of thiophene trimer derivatives substituted with phenylvinyl groups

Conference Paper


Abstract


  • The results of investigations concerning electrochemical properties of two thiophene trimers derivatives substituted with phenylvinyl groups {3′[(E)-2-phenylethenyl]-2,2′:5′,2″-thiophene (monomer A) and 4,4″-didecyloxy-3′[(E)-2-phenylethenyl]-2,2′:5′, 2″-thiophene (monomer B)} and the products of their oxidation were discussed. Electropolymerizations of A and B monomers were carried out with use of cyclic voltammetry and electrochemical measurements were coupled in-situ with spectroscopic methods (UV-Vis, EPR). It was found that A monomer oxidized to oligomers soluble in dichloromethane (Fig. 1-4 and 7) while monomer B showed ability to form stable conductive polymer layers showing low-energy forbidden band (1.6 eV) (Fig. 1, 5, 6 and 8, 9).
