Abstract
A thiophene compound represented by formula (I): in which: A represents a C2–C5 alkylene bridge; R represents a stereoselectively substituted, linear or branched C2–C24 alkyl, C3–C18 cycloalkyl, C1–C18 alkoxy or polyethyleneoxide group, optionally substituted with at least one substituent selected from the group consisting of an alcohol, amide, ether, ester or sulfonate group; or an optionally substituted aryl group having at least one chiral center substituted at said C2–C5 alkylene bridge; polymers derived therefrom; a process for polymerizing a thiophene according to formula (I), optionally chemically or electrochemically; and dispersions, pastes and layers containing polymers derived therefrom.
