COMPOUND FOR ORGANIC ELECTROLUMINESCENT ELEMENTS, AND ORGANIC ELECTROLUMINESCENT ELEMENT |
摘要 |
Provided are an organic EL device practically satisfactory in terms of its light-emitting characteristics, driving voltage, and durability, and a compound for an organic EL device to be used in the device. The organic EL device has a structure in which an anode, a plurality of organic layers including a light-emitting layer, and a cathode are laminated on a substrate, and the organic EL device contains an indolocarbazole compound in at least one organic layer selected from the light-emitting layer, a hole-transporting layer, an electron-transporting layer, a hole-blocking layer, and an electron-blocking layer. The indolocarbazole compound is a compound having, in a molecule thereof , at least one boron-containing group having such a structure that boron of the boron-containing group is bonded to an atom on a linking group bonded to a nitrogen atom of an indolocarbazole ring or to a carbon atom of the ring. |
