The present invention provides a blue light emitting compound comprising (1) a hole transporting core portion, which hole transporting core portion comprises a tertiary nitrogen portion; and (2) at least three electron transporting arm portions extending from the core portion, each electron transporting arm portion comprising an electron transporting portion and an emissive portion.
There is provided conductive organic arylamine compounds. The compounds may be prepared as films and such films may be used as a hole transporting layer, an emissive layer or an electron transporting layer in organic light emitting devices.
