Abstract (en)
[origin: WO0190212A1] The invention relates to polythiophenes of the formula (II), wherein Y = formula (III), formula (IV) or formula (V); Z = alkyl, aryl or alkylaryl; u = 0 or 1; m = 0 to 5; n = 2 to 500; X = (CH2)p+q or (CH2)p-O-(CH2)q; p, q = independently of one another 0 to 10 and R and R' independently of one another are identical to or different from H, represent a linear or branched C1 to C18 alkyl or alkoxy group or a linear or branched C1 to C18 alkyl or alkoxy sulfonate group. Said polythiophenes can be modified using the active ester function and have excellent electrical and optical properties.
