Abstract
Polythiophenes of the formula II 1 Z=alky, 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 are each, independently of one another, from 0 to 10 and R, R′ are identical or different and are each, independently of one another, H, a linear or branched C1-C18 alkyl or alkoxy radical or a linear or branched C1-C18 alkylsulfonate or alkoxysulfonate radical, can be modified via the active ester function and have excellent electrical and optical properties.
