    Abstract: An organic electroluminescence device includes: a first electrode; a second electrode disposed on the first electrode; and at least one organic layer disposed between the first electrode and the second electrode. wherein the at least one organic layer includes a polycyclic compound having a core structure including a n,n′-bicarbazole moiety and, outside the core structure, at least one optionally substituted carbazole group, and the substituted or unsubstituted carbazole groups of the core structure substituted at any one among carbon atoms at position n±1 of the n,n′-bicarbazole moiety, and any one among carbon atoms at position n′±1 of the n,n′-bicarbazole moiety, respectively; and n and n′ are, independently from one another, integers of 1 to 4 (where n±1 and n′±1 are not 0).

    Abstract: An organic electroluminescence device includes a first electrode, a hole transport region, an emission layer including a nitrogen-containing compound, an electron transport region, and a second electrode. The nitrogen-containing compound may include a heterocyclic moiety and two carbazole moieties, the heterocyclic moiety may be a substituted pyridine, a substituted pyrimidine, or a substituted 1,3,5-triazine, each of two carbons among carbons of 2-, 4-, and 6-positions of the substituted pyridine, the substituted pyrimidine, or the substituted 1,3,5-triazine may be substituted with a phenylene group, a carbon in an ortho position of each phenylene group may be linked with a nitrogen at a 9-position of one of the carbazole moieties, and the remaining carbon among the carbons of the 2-, 4-, and 6-positions may be substituted with a substituted or unsubstituted aromatic group, and the carbazole moieties may be linked together by a linker.
