Provided is a compound having an indolo[3,2,1-jk]carbazole skeleton and a heterocyclic skeleton which are bonded to each other through an arylene group. The heterocyclic skeleton contains an imidazole skeleton, a pyrazine skeleton, a pyrimidine skeleton, a triazole skeleton, or a condensed heteroaromatic ring including any of these heterocycles. The high carrier-transport property and the large band gap of the compound allows the used as a host material of a phosphorescent dopant, leading to the formation of a green to blue emissive phosphorescent light-emitting element having high emission efficiency, low driving voltage, and reduced power consumption.
提供的是一种化合物,其具有indolo [3,2,1-jk] carbazole骨架和杂环骨架,通过芳基基团彼此连接。杂环骨架包含咪唑骨架、吡嗪骨架、嘧啶骨架、三唑骨架或包括这些杂环的缩合杂环芳香环。该化合物具有高载流子传输性能和大带隙,可以用作荧光掺杂剂的主体材料,形成具有高发射效率、低驱动电压和降低功耗的绿色到蓝色发光荧光元件。
