TECHNOLOGY FOCUS - POLYMERS - Preferred Complex: In the complex, the functionalized polyketone comprises recurring units of the general formula (I).Ar1 and Ar2=can be identical or different, and are optionally substituted aromatics;R1=an optionally substituted organic radical with 1-80 carbon atoms, a (-CO-) group or an oxygen atom; andn=an integer from 5-5000.The functionalized polyketone comprises recurring units of the general formula (II), (IIa), (III), (IV), (V), and/or (VI).Ar1 and Ar2=can be identical or different and represent an aromatic;X1 and X2=can be identical or different and each represent a sulfonic acid, sulfonate, phosphonic acid, phosphonate, carboxylic acid or carboxylate group;a and b=can be identical or different and each independently of each other represent an integer or non-integer in a range of 0-2, non-integers meaning that the acid mentioned does not occur in every recurring unit, but only in the corresponding fraction of the recurring units; andM=a metal cation or H.The conductive polymer comprises optionally substituted polythiophenes comprising recurring units of the general formula (VII).R4 and R5=independently of each other each represent H, an optionally substituted 1-18C-alkyl radical or an optionally substituted 1-18C-alkoxy radical, R4 and R5 together represent an optionally substituted 1-8C-alkylene radical, where one or more C atoms can be replaced by one or more identical or different hetero atoms selected from O or S, preferably a 1-8C-dioxyalkylene radical, an optionally substituted 1-8C-oxythiaalkylene radical or an optionally substituted 1-8C-dithiaalkylene radical, or represent an optionally substituted 1-8C-alkylidene radical, where optionally at least one C atom is replaced by a hetero atom selected from O or S.The polythiophene comprises recurring units of the general formula (VII-a) and/or (VII-b).A=an optionally substituted 1-5C-alkylene radical, preferably an optionally substituted 2-3C-alkylene radical;Y=O or S;R6=a linear or branched, optionally substituted 1-18C-alkyl radical, preferably linear or branched, optionally substituted 1-14C-alkyl radical, an optionally substituted 5-12C-cycloalkyl radical, an optionally substituted 6-14C-aryl radical, an optionally substituted 7-18C-aralkyl radical, an optionally substituted 7-18C-alkaryl radical, an optionally substituted 1-4C-hydroxyalkyl radical or a hydroxyl radical; andy=an integer from 0-8, preferably 0 or 1, and where in the case where several radicals R6 are bonded to A, these can be identical or different.The polythiophene is poly(3,4-ethylenedioxythiophene). The complex is dispersed or dissolved in one or more dispersing agents. The dispersion has a pH in a range of 1-8. Preferred Component: The electronic component is an organic light-emitting diode or an organic solar cell. EXAMPLE - No suitable example given.
