TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preparation (disclosed): Phenyl-pyrene compound of formula (2) is subjected to cyclization reaction in presence of metal catalyst, to obtain indenopyrene compound (1).X=leaving group. Preferred Definitions:    at least one of R2,R3 and R9=disubstituted amino group (2) substituted by 1-40C group;    R13,R14=6-40C optionally substituted aryl;and    R1,R4,R5-R8,R10-R12=H.    SPECIFIC COMPOUNDS - 27 indenopyrene compounds are disclosed e.g. N,N-diphenylhexacyclo(16.3.1.02,7.08,21.011,20.014,19)docosa-1(22),2(7),3,5,8(21),9,11(20),12,14,16,18-undecaen-4-amine of formula (1a), N,N-diphenylhexacyclo(16.3.1.02,7.08,21.011,20.014,19)docosa-1(22),2,4,6,8(21),9,11(20),12,14(19),15,17-undecaen-5-amine, N,N-diphenylhexacyclo(16.3.1.02,7.08,21.011,20.014,19)docosa-1(22),2,4,6,8(21),9,11(20),12,14(19),15,17-undecaen-15-amine, N-phenyl-N-(4-phenylphenyl)hexacyclo(16.3.1.02,7.08,21.011,20.014,19)docosa-1(22),2,4,6,8(21),9,11(20),12,14(19),15,17-undecaen-4-amine and N-(naphthalen-1-yl)-N-phenylhexacyclo(16.3.1.02,7.08,21.011,20.014,19)docosa-1(22),2,4,6,8(21),9,11(20),12,14(19),15,17-undecaen-4-amine.    EXAMPLE - 1-(2,4-Dibromo-phenyl)-pyrene (in g) and diphenyl amine (1.4), tris(dibenzylidene acetone)dipalladium (0.1), 2,2'-bis(diphenyl phosphino)-1,1'-binapthyl (0.2) and sodium-t-butoxide (1) were suspended in anhydrous toluene (20 ml) in nitrogen atmosphere, refluxed for 10 hours, filtered using silica gel pad, washed using toluene and purified, to obtain (3-bromo-4-pyren-1-yl-phenyl)-diphenyl-amine. The obtained (3-bromo-4-pyren-1-yl-phenyl)-diphenyl-amine (1.7), dichloro bis(triphenylphosphine)palladium (II) (0.23) and 1,8-diazabicyclo(5.4.0 )-7-undecene (0.7) were dissolved in anhydrous dimethyl formamide (15 ml), stirred at 140 degrees C for 11 hours, the reaction mixture was diluted with toluene (150 ml), washed using water (100 ml) and saturated salt solution (50 ml), dried using anhydrous magnesium sulfate, and recrystallized with ethanol (30 ml) and toluene (100 ml), to obtain N,N-diphenylhexacyclo(16.3.1.02,7.08,21.011,20.014,19)docosa-1(22),2(7),3,5,8(21),9,11(20),12,14,16,18-undecaen-4-amine (1a) in an yield of 85%.
