TECHNOLOGY FOCUS - ELECTRONICS - Preferred Components: The electronic device comprises anode, cathode, emitting layer, one or more hole injection layer, hole carrier layer, hole block layer, electron carrier layer, electron injection layer, electron block layer, charge generator and/or further emitting layers, where the presence of all the layers are not necessary.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preparation (Claimed): Preparation of (Q), from dihaloanthraquinone, comprises adding an arylmetal compound and reducing to anthracene; coupling the anthracene with a functionalized aromates, optionally after transformation of the halo group into a boronic acid derivative, and ring closing under acid conditions. SPECIFIC COMPOUNDS - 134 Compounds (I) are disclosed e.g. 2,3,8,9-dibenzo-1,1,7,7-tetraphenyl-5,11-diphenyl-1,7-dihydro-dicyclopenta(b,i)anthracene of formula (Ia), 2,3-benzo-1,1-diphenyl-5,11-diphenyl-1-dihydrocyclopenta(b)anthracene, 8,16-dimethylene-6,14-diphenyl-8,16-dihydrodiindeno(1,2-b:1',2'-i)anthracene, 6,14-diphenyl-8,16-di(propan-2-ylidene)-8,16-dihydrodiindeno(1,2-b:1',2'-i)anthracene and 8,16-bis(diphenylmethylene)-6,14-diphenyl-8,16-dihydrodiindeno(1,2-b:1',2'-i)anthracene.    EXAMPLE - 9,10-Diphenylanthracen-2,6-diboronic acid pinacol ester (9.4 g) were heated for 4 hours in a mixture of ethanol (115 ml), toluene (115 ml), 2M sodium carbonate solution (60 ml), methyl-2-bromobenzoate (4.5 ml) and tetrakis(triphenylphosphine)palladium (750 mg). The reaction mixture was then poured into a mixture of ice water/methanol/hydrochloric aid in a ratio of 1:1:1, washed and dried. The solid residue was dissolved in toluene and filtered. The filtrate was reacted with heptane to obtain 9,10-diphenyl-2,6-(2-carboxymethylphenyl)anthracene (8.9 g). 9,10-Diphenyl-2,6-(2-carboxymethylphenyl)anthracene (8.9 g) was reacted with 0.5M phenylmagnesiumbromide solution (180 ml) in tetrahydrofuran and heated for 3 hours. After this time, 50% acetic acid (50 ml) was added and the solvent was removed. The obtained solid material was dissolved in methanol, washed and dried with methanol to obtain (2-(6-(2-(hydroxy-diphenyl-methyl)-phenyl)-9,10-diphenyl-anthracen-2-yl)-phenyl)-diphenyl-methanol (11.3 g). (2-(6-(2-(Hydroxy-diphenyl-methyl)-phenyl)-9,10-diphenyl-anthracen-2-yl)-phenyl)-diphenyl-methanol (10.3 g) was heated in a mixture of acetic acid (70 ml) and concentrated hydrochloric acid (1 ml) for 2 hours. The unusual solid material was removed from the mixture, washed and dried with water, ethanol and heptane. The mixture was four times recrystallized from chlorobenzene to obtain 2,3,8,9-dibenzo-1,1,7,7-tetraphenyl-5,11-diphenyl-1,7-dihydro-dicyclopenta(b,i)anthracene (6 g).
