Towards functionalised terthiophene-based polymers

Terthiophenes functionalised with nitro, amino, cyano, carboxyl, decylcarboxylate, acetic and acrylic acid groups were synthesized using Suzuki coupling. The electrochemical polymerization and spectroscopic data of the films deposited from substituted terthiophene modified at the 3′-position with electron-donating (NH2) and electron-withdrawing (NO2, COOC10H21) groups have been investigated. In addition, effect of alkoxy groups on the electrochemical production of substituted poly(terthiophenes) and characterization of the resulting polymer film was studied.
