NOVELTY - Polymer (I) comprising one or more fluorinated structure elements (IA) is new.    USE - (I) is useful for functioning as charge transport, charge injection, hole transport, hole injection, emission, charge block, morphology-, rheology- or processability-enhancement in an organic electronic devices, such as organic LED, organic integrated circuit, organic field-effect transistor, organic thin-film transistor, organic solar cell, organic laser diode, organic photo-voltaic element or device, or an organic photoreceptor (all claimed).    ADVANTAGE - (I) exhibits high solubility and provides organic electronic devices with high quality, lifetime and power efficiency.    DETAILED DESCRIPTION - Polymer (I) comprising one or more fluorinated structure elements of formula (-(M)a((R1f)b)-) (IA) is new.    M = (hetero)aryl or aliphatically bridged aromatic ring system, which is optionally substituted by one or more R1, where: M bonds to adjacent structure units and can have two bonds, and the polymer is selectively further not substituted with partially fluorinated residue R1f and contains M , provided that the sum of M is 2-10000;    a = 1-10000;    b = 1-10;    R1f = cyclic fluorinated 1-60C-organic substituent, which is optionally saturated, where one or more non-adjacent CH2 groups are optionally replaced by O, S, Se, Te, Si(R2)2, Ge(R2)2, BR2, NR2, PR2, C=O, C=S, C=Se, C=NR2, PO(R2), PS(R2), R2C=CR2, C?=C, SO, SO2, COO, O(CO)O or CONR2, provided that R1f is not completely fluorinated, i.e. at least a free position of the carbon backbone of R1f is substituted with F, and two or more R1f are bonded with M or at two or more different adjacent or non-adjacent group M forms an aliphatic, unsaturated or aromatic ring system;    R1 = H, F, aliphatic, (hetero)aryl 1-20C-hydrocarbon, in which one or more H atoms are optionally replaced by F, where one or more adjacent or non-adjacent CH2 groups are optionally replaced by O, S, Se, Te, Si(R2)2, Ge(R2)2, BR2, NR2, PR2, CO, C=S, C=Se, C=NR2, PO(R2), PS(R2), R2C=CR2, C?=C, SO, SO2, COO, O(CO)O or CONR2, provided that two or more R1 are bonded to M or at two or more different adjacent or non-adjacent M forms an aliphatic, unsaturated or aromatic ring system; and    R2 = H, F or an aliphatic or (hetero)aryl 1-20C-hydrocarbon, in which one or more H are optionally replaced by F.    INDEPENDENT CLAIMS are included for:    (1) a compound of formula (M(X)n(R1f)b) (XXXV);    (2) a mixture comprising (I) and further one or more compounds of polymers, oligomers, dendritic and low molecular substances;    (3) a formulation comprising (I) and at least a solvent; and    (4) an organic electronic device comprising one or more active layers, where at least one of the active layers comprises (I).    X = a leaving group suitable for the polymerization reaction, preferably halo, O-tosylate, O-triflate, O-sulfonate, boronic acid ester, partially fluorinated silyl group, diazonium group and tin organic compounds; and    n = 1-3.
