SPECIFIC COMPOUNDS - 22 aromatic-amine derivatives are disclosed. e.g. (9,9-dimethyl-7-((E)-2-(4-(phenyl-(4-trimethylsilanyl-phenyl)-amino)-phenyl)-vinyl)-9H-fluoren-2-yl)-phenyl-(4-trimethylsilanyl-phenyl)-amine of formula (Ia), (7-((E)-2-(4-((3,5-dimethyl-phenyl)-phenyl-amino)-phenyl)-vinyl)-9,9-dimethyl-9H-fluoren-2-yl)-phenyl-(4-trimethylsilanyl-phenyl)-amine, (4-dimethylsilanyl-phenyl)-(7-((E)-2-(4-diphenylamino-phenyl)-vinyl)-phenanthren-2-yl)-phenyl-amine, (7-((E)-2-(4-(bis-(4-trimethylsilanyl-phenyl)-amino)-phenyl)-vinyl)-9,9-dimethyl-9H-fluoren-2-yl)-bis-(4-trimethylsilanyl-phenyl)-amine and N-(4-((E)-2-(4-(4-(naphthalen-2-yl(4-(trimethylsilyl)phenyl)amino)phenyl)naphthalen-1-yl)ethenyl)phenyl)-N-phenylnaphthalen-2-amine.    EXAMPLE - 1-Bromo-4-(trimethyl silyl) benzene (in g) (27.5), aniline (33.5), tris(dibenzylidene acetone) dipalladium (1.65), 2,2'-bis(diphenylphosphino)-1,1'-binaphthyl (2.24), sodium tert-butoxide (23) and toluene were reacted at 100 degrees C for 6 hours, cooled, filtered, concentrated, purified and dried to obtain intermediate material (m1) (23.1). 2-Bromo-7-iodo-9,9-dimethyl fluorene (41.9), dehydrated tetrahydrofuran (300 mL), 1.6 M-n-butyllithium hexane solution (72 mL), dehydrated N,N-dimethylformamide (25 mL), 4 N-hydrochloric acid and toluene were mixed, reacted, liquid-separated, extracted, washed, dried and refined to obtain intermediate material (m2) (24.4). Diethyl phosphonate(4-bromo benzyl) (8.40), tetrahydrofuran (50 mL), potassium tert-butoxide (6.16), and tetrahydrofuran solution (60 mL) of intermediate material (m2) (6.9) were reacted for 2 hours, heated, liquid-separated, extracted, washed, recrystallized, concentrated and dried to obtain intermediate material (m3) (7). Intermediate material (m3) (4.5), sodium tert-butoxide (1.9), intermediate material (m1) (5.5), palladium (II) acetate (133 mg), tri-tert-butylphosphine (121 mg) and toluene were reacted at 90 degrees C for 10 hours, cooled, filtered, concentrated, refined, recrystallized and dried to obtain (9,9-dimethyl-7-((E)-2-(4-(phenyl-(4-trimethylsilanyl-phenyl)-amino)-phenyl)-vinyl)-9H-fluoren-2-yl)-phenyl-(4-trimethylsilanyl-phenyl)-amine (2.7).
