SPECIFIC COMPOUNDS - 83 Aromatic amine derivatives are disclosed e.g. 4-((6-((4-cyanophenyl)(phenyl)amino)-3,8-dimethylpyren-1-yl)(phenyl)amino)benzonitrile of formula (Ia), 3-((6-((3-cyanophenyl)(phenyl)amino)-3,8-dimethylpyren-1-yl)(phenyl)amino)benzonitrile, 2-((6-((2-cyanophenyl)(phenyl)amino)-dimethylpyren-3,8-1-yl)(phenyl)amino)benzonitrile, 4-((6-((4-cyanophenyl)(4-methylphenyl)amino)-3,8-dimethylpyren-1-yl)(4-methylphenyl)amino)benzonitrile and 4-((6-((4-cyanophenyl)(4-(propan-2-yl)phenyl)amino)-3-methyl-8-(propan-2-yl)pyren-1-yl)(4-methylphenyl)amino)benzonitrile.    EXAMPLE - 4-Bromobenzonitrile (in g) (20), aniline (30 mL), tris(diphenylideneacetone)dipalladium (1.5), 2,2'-bis(diphenylphosphino)-1,1'-binaphthyl (2.1), sodium tert-butoxide (21.1) and dehydrated toluene (313 mL) were mixed at 85 degrees C for 6 hours, purified, filtered and dried to obtain 4-cyanophenyl phenylamine (14.9). 4-Cyanophenyl phenylamine (7.2), 1,6-dibromo-3,8-dimethylpyrene (5.7), sodium t-butoxide (2.8), palladium acetate (160 mg), tri-t-butylphosphine (135 mg) and dehydrated toluene (73 mL) were added and mixed at 85 degrees C for 7 hours.
