摘要：
Disclosed are an organic electroluminescent device that is improved in luminous efficiency, sufficiently secures driving stability, and has a simple construction, and a material to be used in the device. The material is a material for an organic electroluminescent device formed of a carborane ring compound having a structure in which two indolocarbazole groups are each bonded to a carborane ring through an aromatic group. In addition, the device is an organic electroluminescent device having organic layers between an anode and a cathode laminated on a substrate, in which at least one layer of the organic layers contains the material for an organic electroluminescent device. When the organic layer is a light-emitting layer, the layer contains a phosphorescent light-emitting dopant and contains the material for an organic electroluminescent device as a host material.
摘要（中）：
本发明公开了一种有机电致发光器件，其发光效率得到改善，充分确保了驱动稳定性，并且具有简单的结构以及用于该器件的材料。 该材料是用于由碳硼烷环化合物形成的有机电致发光器件的材料，所述碳硼烷环化合物具有其中两个吲哚并咔唑基各自通过芳族基团与碳硼环结合的结构。 另外，该器件是在基板上层叠阳极和阴极之间具有有机层的有机电致发光器件，其中至少一层有机层含有用于有机电致发光器件的材料。 当有机层是发光层时，该层含有磷光发光掺杂剂并且包含用于有机电致发光装置的材料作为主体材料。
