Novel organic compounds comprising a bicarbazole core are provided. In particular, the compound has a 3;3′-bicarbazole core substituted at the 9
th
position with at least one of dibenzofuran, dibenzothiophene, dibenzoselenophene, azadibenzofuran, azadibenzothiophene and azadibenzoselenophene. The compounds may be used in organic light emitting devices to provide devices having improved efficiency and improved lifetime.
Compounds comprising an aza-dibenzo moiety and a condensed aromatic moiety having at least three benzene rings are provided. In particular, the compounds may comprise an azadibenzofuran, azadibenzothiophene, or azadibenzoselenophene joined directly or indirectly to an anthracene. The compounds may be used in the electron transport layer of organic light emitting devices to provide devices with improved properties.
The present disclosure provides novel compounds containing dibenzo[fg,op]tetracene and larger all-benzenoid moiety that can be used as hosts for phosphorescent emitters providing low-voltage, high-efficiency and high-stability devices.
