SPECIFIC COMPOUNDS - 70 Aromatic amine derivatives are disclosed, such as 6-N,12-N-bis((8-oxatricyclo(7.4.0.0)trideca-1(9),2(7),3,5,10,12-hexaen-4-yl))-6-N,12-N-diphenylchrysene-6,12-diamine of formula (D1), 6-N,12-N-bis(4-methylphenyl)-6-N,12-N-bis((8-oxatricyclo(7.4.0.0)trideca-1(9),2(7),3,5,10,12-hexaen-4-yl))chrysene-6,12-diamine, 6-N,12-N-bis((8-oxatricyclo(7.4.0.0)trideca-1(9),2(7),3,5,10,12-hexaen-4-yl))-6-N,12-N-bis(4-(propan-2-yl)phenyl)chrysene-6,12-diamine, 6-N,12-N-bis(3,5-dimethylphenyl)-6-N,12-N-bis((8-oxatricyclo(7.4.0.0)trideca-1(9),2(7),3,5,10,12-hexaen-4-yl))chrysene-6,12-diamine, and 6-N,12-N-bis(naphthalen-2-yl)-6-N,12-N-bis((8-oxatricyclo(7.4.0.0)trideca-1(9),2(7),3,5,10,12-hexaen-4-yl))chrysene-6,12-diamine.    EXAMPLE - N-(2-dibenzofuranyl) N-phenyl acetamide (in g) (7.9), potassium hydroxide (8.8), water (10 ml), ethanol (25 ml) and toluene (50 ml) were refluxed to obtain N-(2-dibenzofuranyl) N-phenyl amine. The obtained compound (4.2), 6-12-dibromo-chrysene (2.8), t-butoxy sodium (4.3), toluene (20 ml) and tris(dibenzylidene acetone)dipalladium (186 mg) were reacted at 80 degrees C for 4 hours, filtered and dried under reduced pressure to obtain 6-N,12-N-bis((8-oxatricyclo(7.4.0.0)trideca-1(9),2(7),3,5,10,12-hexaen-4-yl))-6-N,12-N-diphenylchrysene-6,12-diamine.
