SPECIFIC COMPOUNDS - 32 Carbazole group-containing compounds are specifically claimed e.g. 13-(4-diphenyl)-1,13-diazapentacyclo(10.7.1.02,7.08,20.014,19)icosa-2(7),3,5,8(20),9,11,14(19),15,17-nonaene of formula (IA), 13-(4-(naphthalen-2-yl)phenyl)-1,13-diazapentacyclo(10.7.1.02,7.08,20.014,19)icosa-2(7),3,5,8(20),9,11,14(19),15,17-nonaene, 13-(2,6-diphenylpyridin-4-yl)-1,13-diazapentacyclo(10.7.1.02,7.08,20.014,19)icosa-2(7),3,5,8(20),9,11,14(19),15,17-nonaene, 13-(4-(2,6-diphenylpyridin-4-yl)phenyl)-1,13-diazapentacyclo(10.7.1.02,7.08,20.014,19)icosa-2(7),3,5,8(20),9,11,14(19),15,17-nonaene and 13-(4-(imidazo(1,2-a)pyridin-2-yl)phenyl)-1,13-diazapentacyclo(10.7.1.02,7.08,20.014,19)icosa-2(7),3,5,8(20),9,11,14(19),15,17-nonaene.    EXAMPLE - Carbazole, 2-bromonitrobenzene, tris(dibenzylideneacetone)dipalladium, tri-tert-butylphosphine and sodium t-butoxide were mixed and dissolved in toluene. The reaction mixture was then refluxed at 110 degrees C for 24 hours and filtered. The filtrate was cooled and recrystallized using toluene and acetone, to obtain 9-(2-nitrophenyl)-9H-carbazole. The obtained product was dissolved in o-dichlorobenzene, and triphenylphosphine was added. The reaction mixture was refluxed for 24 hours, and the solvent was distilled off under reduced pressure. The obtained residue was purified using column chromatography, to obtain 1,13-diazapentacyclo(10.7.1.02,7.08,20.014,19)icosa-2(7),3,5,8(20),9,11,14(19),15,17-nonaene (a) with yield of 53%. Iodobiphenyl, tris(dibenzylideneacetone)dipalladium, tri-tert-butylphosphine and sodium t-butoxide were added to the obtained compound (a), and the mixture was dissolved in toluene. The reaction mixture was refluxed at 110 degrees C for 24 hours and filtered. The filtrate was then cooled and recrystallized using toluene and acetone, to obtain 13-(4-diphenyl)-1,13-diazapentacyclo(10.7.1.02,7.08,20.014,19)icosa-2(7),3,5,8(20),9,11,14(19),15,17-nonaene (IA) with yield of 68%.
