Abstract: Disclosed is a triphenylene based aromatic compound, wherein a benzene center is substituted with a triphenylene group and another aromatic group such as triphenylenyl, pyrenyl, phenylvinyl, carbazolylphenyl, or arylanthryl in the meta position of the benzene center. The meta-substituted aromatic compound of the invention has better thermal stability (Tg) than the conventional para-substituted aromatic compound. The meta-substituted aromatic compound, served as a hole transporting layer or a host material applied in a light emitting layer in an OLED, is more preferable than the conventional para-substituted aromatic compound.
