TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preparation: No general preparation given. Preferred Layer: The light emitting layer contains condensed polycyclic compound as a host material and a phosphorescent emitting material. The phosphorescent emitting material is ortho-metalated complex of metal atom chosen from iridium, osmium and platinum. The element further has an electron injection layer between cathode and light emitting layer, an electron carrying layer between cathode and light emitting layer, and a positive hole transport layer between anode and light emitting layer. The electron injection layer contains nitrogen-containing ring derivative. The electron carrying layer and positive hole transport layer contain organic electroluminescent element material containing the polycyclic compound. A reducing dopant is added to the interface of cathode and organic thin film layer. SPECIFIC COMPOUNDS - 230 Condensed polycyclic compounds (I) are disclosed e.g. 3-(phenanthren-9-yl)-20-phenyl-3,20-diazapentacyclo(11.7.0.02,10.04,9.014,19)icosa-1(13),2(10),3,5,7,11,14(19),15,17-nonaene, 20-phenyl-3-(tetracyclo(8.8.0.02,7.013,18)octadeca-1(18),2,4,6,8,10,12,14,16-nonaen-8-yl)-3,20-diazapentacyclo(11.7.0.02,10.04,9.014,19)icosa-1(13),2(10),3,5,7,11,14(19),15,17-nonaene, 20-phenyl-3-(triphenylen-2-yl)-3,20-diazapentacyclo(11.7.0.02,10.04,9.014,19)icosa-1(13),2(10),3,5,7,11,14(19),15,17-nonaene, 3-(pentacyclo(12.8.0.02,7.08,13.015,20)docosa-1(22),2,4,6,8,10,12,14,16,18,20-undecaen-21-yl)-20-phenyl-3,20-diazapentacyclo(11.7.0.02,10.04,9.014,19)icosa-1(13),2(10),3,5,7,11,14(19),15,17-nonaene and 3-(phenanthren-3-yl)-20-phenyl-3,20-diazapentacyclo(11.7.0.02,10.04,9.014,19)icosa-1(13),2(10),3,5,7,11,14(19),15,17-nonaene.    EXAMPLE - 20-phenyl-3,20-diazapentacyclo(11.7.0.02,10.04,9.014,19)icosa-1(13),2(10),3,5,7,11,14(19),15,17-nonaene (in g) (3.3), 9-bromo-phenanthrene (5.1), copper iodide (1.9), trans-1,2-cyclohexanediamine (3.4), and tribasic pottasium phosphate (6.4) were added to dehydrated N,N-dimethylacetamide (100 ml), heating-refluxed in argon atmosphere and stirred for 96 hours. Toluene (500 ml) was added to residue obtained by concentrating reaction solution under reduced pressure, and heated at 120 degrees C. The insoluble material was separated by filtration. The filtrate was concentrated under reduced pressure and purified. 3-(Phenanthren-9-yl)-20-phenyl-3,20-diazapentacyclo(11.7.0.02,10.04,9.014,19)icosa-1(13),2(10),3,5,7,11,14(19),15,17-nonaene (0.6) was obtained as pale yellow solid at yield of 12% with molecular weight of 508.
