Novel triphenylene compounds are provided. Specific examples include multi-aryl-substituted triphenylenes. A preferred group of compounds 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. Some high triplet energy analogs are expected to work with deep blue phosphorescent dopants. The compounds may be useful in phosphorescent organic light emitting devices. Also provided is an organic electroluminescent device comprising an anode, a cathode, and an emissive layer between the anode and the cathode, the emissive layer comprising a phosphorescent material and a compound having a repeat unit, the repeat unit containing a triphenylene moiety.
提供了新型三苯基烯化合物。具体例子包括多芳基取代的三苯基烯。首选化合物组是取代有一个或多个间位取代基的非融合芳基基团的三苯基烯,其中每个间位取代基是一个非融合芳基基团,可选地取代有选择自非融合芳基基团和烷基的进一步取代基。另一首选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基团的三苯基烯,其中每个间位取代基是一个非融合芳基或杂芳基基团,可选地取代有选择自非融合芳基基团、非融合杂芳基基团和烷基的进一步取代基。预计一些高三重态能量的类似物将与深蓝色磷光掺杂剂配合使用。这些化合物可能在磷光有机发光器件中有用。还提供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射层,该发射层包括磷光材料和具有重复单元的化合物,重复单元含有三苯基烯基团。
