A novel compound based on aza- and diazodibenzofurans; aza- and diaza dibenzothiophenes, such as benzothieno- and benzofuropyrimidines as well as benzothieno- and benzofuropyrazines useful for electron-transporting host material in green, red, yellow, and white phosphorescent emitting devices is disclosed.
The present disclosure provides novel compounds based on azadibenzothiophenes, azadibenzofurans and azadibenzoselenophenes with at least two nitrogen atoms in the aza rings. The compounds can be used in green, red, yellow and white emitting devices as electron-transporting hosts.
