NOVELTY - Organic electronic devices, comprises at least one organic layer and at least an aromatic boronic acid or borinic acid derivative.    USE - The organic electronic devices are useful as organic or polymer light emitting diodes (OLEDs, PLEDs), organic field-effect transistors (O-FETs), organic thin film transistors (O-TFTs), organic lightemitting transistors (O-LETs), organic integrated circuits (O-ICs), organic solar cells (O-SCS), organic field quench devices (O-FQDs), organic light-emitting cells (LECs), organic photoreceptors or organic laser diodes (O-lasers). The boronic acid and/or borinic acid derivatives are used as electron transportation material, as pure substance or in a mixture of electron transport layer; as pure substance in hole blocking material or in a mixture of used in hole blocking layer. The boronic acid and/or borinic acid derivative is used as hole transportation material, as pure substance or in a mixture of a hole transport layer or in a hole injection layer in an organic electronic device. The boronic acid and/or borinic acid derivative is used as fluorescent or phosphorescing dopant, preferably in combination with one host material, in an emission layer in a fluorescent and/or phosphorescing organic electroluminescence device. The aromatic boronic acid and/or borinic acid derivatives or oligomers, polymers or dendrimers are useful in organic electronic devices (all claimed).    ADVANTAGE - The organic electronic devices exhibits good efficiency, high life lasting and are simply accessible. The boronic acid and/or borinic acid derivative increases the efficiency and the life span of the organic electronic device.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for:    (1) preparation of polymers containing boronic acid derivatives, comprising reaction of an aliphatic or aromatic bis(diols), bis(dithiols) or bis(diamine) or corresponding highly replaced compounds with an aromatic bisboronic acid or higher boronic acid in a polycondensation reaction or by reaction of an aromatic compound that contains two hydoxy-, thiol- or amino groups with boronic acid groups;    (2) 29 aromatic boron compounds e.g. borinic acid derivative of formula (5-8); and    (3) an oligomer, polymer and dendrimer containing at least one boronic acid or borinic acid derivative, under the condition that the boronic acid and/or borinic acid derivative in oligomer and/or polymer is bound, at least a place in the main chain and/or the side chain and not bounded or not only as end group to the chain ends of the oligomers and/or polymer.    X = N(R2)2, NHR2, OR2, SR2 or OBAr2;    Y1 = Ar or X preferably N(R2)2 or NHR2;    DCy = a cyclic group containing at least one donor atom, preferably N or P, over which the cyclic group is of the metal is bounded, and substituted with R1, where the groups DCy and CCy are bonded together by at least one covalent bond;    CCy = a cyclic group containing a carbon atom, over which the cyclic group of the metal is bounded, and substituted with R1;    A = monoanionic, bidentate chelatinized ligand, preferably a diketonate ligand;    z = 0-6, where in each complex, at least z is not equal to 0 and z is absent, that is larger than the amount of substitutable hydrogen atoms are maximum at the corresponding cycle of DCy and/or CCy; and    R2 = 1-40C alkyl, 3-40C branched or cyclic alkyl (optionally substituted with R3, where one or more non-adjacent C-atoms are replaced by N-R3, O, S, CO, O-CO-O, CO-O, -CR3=CR3 or -C=C-, with the standard that heteroatom is not bonded directly to O, S and/or N of X and Y1, and one or more H-atoms are replaced by F, Cl, Br, I or CN) or aromatic or heteroaromatic ring system with 5-40C aromatic ring atoms (substituted with R3 to be substituted) or a combination of two, three or four of remainders of these systems form, and two or more of R1 forms mono- or polycyclic, aliphatic or aromatic ring system (preferably R2 in combination with B1, X and Y1 forms 5-7 membered ring).
