Preferred Definitions:    R1, R2 = 59 groups e.g. fluorene group of formula (a), phenyl group of formula (b), naphthalene group of formula (c), substituted phenyl groups of formula (d) or (e), bisfluorene group of formula (f), pyrene group of formula (g), perylene group of formula (h), or triphenylene groups of formula (i) or (j);    R11, R12 = 6-60C aryl, 1-30C alkyl(6-30C)aryl or (6-30C)ar(1-30C)alkyl;    R13 = H, 1-60C alkyl, 6-60C aryl, 1-30C alkyl-6-30C aryl or 6-30C ar-1-30C alkyl;    R14-R16 = 6-60C aryl, 1-30C alkyl-6-30C aryl or 6-30C ar(1-30C)alkyl;    R17, R18 = (1-60C)alkyl;    R19 = H or 1-60C alkyl;    R23-R26 = 1-60C alkyl; and    R31, R32 = H or 1-60C alkyl.    SPECIFIC COMPOUNDS - 2651 Compounds (I) are specifically claimed e.g. 9,10-bis-(9,9-diphenyl-9H-fluoren-2-yl)-N,N,N',N'-tetraphenyl-anthracene-2,6-diamine of formula (Ia), 9,10-bis-(9,9-diphenyl-9H-fluoren-2-yl)-N,N,N',N'-tetra-naphthalen-2-yl-anthracene-2,6-diamine, 9,10-bis-(9,9-diphenyl-9H-fluoren-2-yl)-N,N,N',N'-tetra-naphthalen-1-yl-anthracene-2,6-diamine, N,N,N',N'-tetrakis-biphenyl-4-yl-9,10-bis-(9,9-diphenyl-9H-fluoren-2-yl)-anthracene-2,6-diamine and 9,10-bis-(9,9-diphenyl-9H-fluoren-2-yl)-N,N,N',N'-tetra-p-tolyl-anthracene-2,6-diamine.    EXAMPLE - 2,6-Dibromo-9,10-bis-(9,9-diphenyl-9H-fluoren-2-yl)-9,10-dihydro-anthracene-9,10-diol (7 g), potassium iodide (4.64 g), sodium hydrophosphite (4.44 g) and acetic acid (100 ml) were stirred under reflux in a reaction vessel. After 15 hours, water (500 ml) was added, and the mixture was stirred for 1 hour. The precipitate obtained from filtering under reduced pressure was washed three times with water (300 ml) and once with acetone (300 ml). The resulting mixture was recrystallized from dichloromethane (100 ml) and methanol (500 ml) to give 2,6-bibromo-9,10-bis-(9,9-diphenyl-9H-fluoren-2-yl)-anthracene (G). A reaction vessel was charged with (G) (4 g), (4-tert-butyl-phenyl)-phenyl-amine (2.79 g), palladium acetate (II) (0.31 g), tri-tert-butylphosphine (0.2 ml), cesium carbonate (6.05 g), and toluene solvent (50 ml), and the mixture was stirred under reflux in the presence of nitrogen atmosphere. After 8 hours, the mixture was cooled to room temperature, and water (100 ml) was added to quench the reaction. The mixture was extracted with dichloromethane (300 ml) to obtain organic layer, which was dried over magnesium sulfate and distilled under reduced pressure. The organic product thus obtained was purified to obtain N,N'-bis-(4-tert-butyl-phenyl)-9,10-bis-(9,9-diphenyl-9H-fluoren-2-yl)-N,N'-diphenyl-anthracene-2,6-diamine (2.0 g, 38%).
