Dependence of Poly(3-alkylthiophene) Film Properties on Electrochemical Polymerization Conditions and Alkyl Chain Length

Abstract
Conductivity of the poly(3-alkylthiophene) (PAT) films is strongly affected by the conditions of electrochemical polymerization. The oxidation potential is higher and the conductivities lower in the PAT films of longer alkyl chain length. On the other hand, ΔH pp is narrower and the spin concentration higher in the PAT films of shorter alkyl chain length.
