The amount of host material is 0.1-99 (preferably 1-99.9) wt.%. The organic electronic device further comprises an anode, cathode and at least a hole-transmitting or hole-injecting layer, where the hole transporting- and/or hole injecting layer contains (A). In organic electroluminescence device, the emitting compounds are used in same- or different layers.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preparation (Disclosed): Preparation of (A) comprises bromination of quinolizine compounds of formula (III) in the presence of pyridine and dichloro methane to give a brominated quinolizine compounds of formula (IV), and reaction of (IV) with phenyl-boron compounds of formula (V) to give quinolizine-triphenyl compounds of formula (VI) (representative of (A)). Preferred Definitions:    X = N, P or P=O; either    Y1 = O, S, (CR1)2, C=O, P(=O)R1, C=C(R1)2, NR1, SO, SO2 or a chemical bond; and    R1 = a bond to the polymer, N, F, CF3, OCH3, OCF3, or an aliphatic, aromatic or heteroaromatic 1-10C hydrocarbon; or    R1Y1 = 1-6C aliphatic hydrocarbon or 6-10C aryl- or heteroaryl group; or    2R1Y1 = a ring system;    R = a bond to the polymer, F, Cl, Br, I, CHO, B(OR2)2, P(R2)2, N(Ar)2, -R2C=CR2-, -C?=C- or an aromatic or heteroaromatic ring system with 5-30 aromatic ring atoms (substituted with one or more non-aromatic residues of R1 or 2-5 of its residues); and    L = chemical bond, -R2C=CR2-, -C?=C-, C=O, S=O, SO2, -O-, -S-, P(R1)3-p, P(=O)(R1)3-p, Si(R1)4-p, N(Ar)3-p or aromatic or heteroaromatic ring system with 6-30 aromatic ring atoms (substituted by one or more R2 residues).    SPECIFIC COMPOUNDS - 47 compounds (A) specifically disclosed e.g. 4,4,8,8,12,12-hexamethyl-2,6,10-tribromo-4H,8H,12H-benzo(1,9)quinolizino(3,4,5,6,7)acridine of formula (Ia).    EXAMPLE - N-bromo-succinimide (8 g) in dichloro methane (100 ml) was added to 4,4,8,8,12,12-hexamethyl-4H,8H,12H- benzo(1,9)quinolizino(3,4,5,6,7)acridine (5.3 g) in dichloro methane (150 ml) and stirred for 4 hours. To the above mixture, water (150 ml) was added and extracted with dichloro methane. The reaction mixture was worked up to give 4,4,8,8,12,12-hexamethyl-2,6,10-tribromo-4H,8H,12H-benzo(1,9)quinolizino(3,4,5,6,7)acridine (3 g).
