Disclosed is an organic electroluminescent device including an anode, a cathode, and an emissive layer between the anode and the cathode, the emissive layer including a phosphorescent material and a compound having a repeat unit that contains a novel triphenylene moiety. A preferred group of the novel triphenylene moiety are triphenylenes that are substituted with a non-fused aryl group having one or more meta-substituents, where each meta-substituent is a non-fused aryl group optionally substituted with further substituents selected from the group consisting of non-fused aryl groups and alkyl groups. A further preferred group of compounds are triphenylenes that are substituted with a non-fused heteroaryl group having one or more meta-substituents, where each meta-substituent is a non-fused aryl or heteroaryl group optionally substituted with further substituents selected from the group consisting of non-fused aryl groups, non-fused heteroaryl groups, and alkyl groups. The compounds may be useful in phosphorescent organic light emitting devices.
本发明公开了一种有机电致发光装置,包括阳极、阴极和位于阳极和阴极之间的发光层,所述发光层包括一种磷光材料和一个包含新型三苯基烯基重复单元的化合物。新型三苯基烯基的首选基团是三苯基烯基,该基团被取代为具有一个或多个间位取代基的非融合芳基基团,其中每个间位取代基是一个非融合芳基基团,可选择进一步取代为来自非融合芳基基团和烷基的取代基。另一个首选的化合物组是取代有一个或多个间位取代基的非融合杂芳基的三苯基烯基,其中每个间位取代基是一个非融合芳基或杂芳基基团,可选择进一步取代为来自非融合芳基基团、非融合杂芳基基团和烷基的取代基。这些化合物可以用于磷光有机发光装置。
