摘要

正

Three series of polythiophenes containing fluoroalkoxy and fluoroether substituentswere prepared by electrochemical polymerization. The effect of substituents with fluoro-alkoxy or ether functional groups on the electrochemical polymerization of thiophene mono-mers and properties of the obtained polymers were analyzed. The introduction of a flu-oroether functional group at the 3-position of the thiophene ring leads to an increase ofthe oxidation potential of the monomer and to a decrease of the conductivity of the re-sulting polymers

even with the use of a CH

group as spacer. Conversely

the presenceof an oxygen atom directly at the 3-position of the thiophene ring

which offsets the nega-tive withdrawing effect of fluoroalkyl groups

facilitates the synthesis of highly conductingpolythiophenes.
