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).
一种有机电致发光器件包括:第一电极;设置在第一电极上的第二电极;以及设置在第一电极和第二电极之间的至少一个有机层。其中,至少一个有机层包括具有核结构的多环化合物,包括一个n,n'-双咔唑基团,核结构外部,至少一个可选择取代的咔唑基团,以及取代或未取代的咔唑基团,其中n±1位置的碳原子和n'±1位置的碳原子中的任一位置被取代于n,n'-双咔唑基团,分别;n和n'是独立的整数,范围为1至4(其中n±1和n'±1不为0)。
