Abstract
The aim of this work was to determine the effects of substituting the thiophene aromatic hydrogen atom in the 4-position in poly(3-alkylthio phene) (P3AT) by a nitro group (-NO2), or by a chlorine atom (-Cl) in a highly dispersed state of polymer. The feature of such substituted p olymers is lower conductivity in comparison with the initial polymer. Modified P3ATs remain semiconducting in character. The nitration and c hlorination of P3ATs take place mainly in the 4-position of the thioph ene ring. The rates of both processes increase with an increase in the chain length of the alkyl side group.
