-
Paragraph 0175; 0176, (2014/01/08)
A biscarbazole derivative having a specific group, which is represented by formula (1): and an organic electroluminescence device in which a plurality of organic thin-film layers including a light emitting layer are disposed between a cathode and an anode, and at least one of the organic thin-film layers include the biscarbazole derivative. The organic electroluminescence device exhibits high emission efficiency and has a long lifetime. In formula (1), each of A1 and A2 independently represents a substituted or unsubstituted aromatic hydrocarbon group having 6 to 30 ring carbon atoms; each of Y1 to Y16 independently represents C(R) or a nitrogen atom; each of R groups independently represents a hydrogen atom, etc. and each of L1 and L2 independently represents a single bond, etc.; provided that at least one of A1, A2 and R represents a substituted or unsubstituted fluoranthenyl group, etc.
