Synthesis and electrochemical polymerization of some monomers with Schiff base or vinylene structures and thiophene moieties

The synthesis of five monomers with thiophene moieties and conjugated Schif f base or phenylene-vinylene bridges between them was performed. The electr ochemical characterization and MO calculations evidenced the possibility of coupling at the 2,2' positions of the heterocycles. The electrochemical ox idative polymerization of the monomers was carried out in galvanostatic: co nditions. The resulting polymers were characterised by usual spectral metho ds and thermal analysis.
