Abstract
A layer configuration on a support, the layer configuration comprising a non-photoactive element exclusive of poly(3,4-alkylenedioxythiophene)s and poly(3,4-dialkoxythiophene)s, the element containing a first polymer containing structural units according to formula (I):in which X and Y are independently O, S, N—R1, Z is —(CH2)m—CR2R3—(CH2)n—; R1 is aryl, C1-18-alkyl or hydrogen; R2 is hydrogen or —(CH2)s—O—(CH2)p—SO3−M+; R3 is —(CH2)s—O—(CH2)p—SO3−M+; M+ is a cation; m and n are independently a whole number from 0 to 3; s is a whole number from 0 to 10; and p is a whole number from 1 to 18, and a second polymer different from the first polymer and selected from the group consisting of optionally quaternized polyamine-polymers, polysulpho-polymers, polyphosphoric acids and polyphosphoric acid salts, the surface of one side of the element being contiguous with a positive electrode and the surface on the opposite side of the element being contiguous with a material capable of transporting holes.
