ARYLAMINE COMPOUND AND ORGANIC ELECTROLUMINESCENCE DEVICE CONTAINING THE SAME

摘要

Provided are a novel arylamine compound of a specific structure having at least one spiro bond; an organic EL device in which an organic compound layer comprising one layer or plural layers including at least a luminescent layer is interposed between a cathode and an anode, wherein at least one of the above organic compound layers contains the arylamine derivative described above; an organic EL device in which an organic compound layer comprising one layer or plural layers including at least a luminescent layer is interposed between a cathode and an anode, wherein at least one of the above organic compound layers contains the arylamine derivative described above and a luminescent material; and an organic EL device in which an organic compound layer comprising one layer or plural layers including at least a luminescent layer is interposed between a cathode and an anode, wherein the above organic compound layer is prepared by laminating a hole transporting layer containing the arylamine derivative described above and a luminescent layer comprising a phosphorescence-emitting metal complex and a host material. Provided are an organic EL device which has a high luminance, a high heat resistance and a long life and which is excellent in a hole transporting property and has a high luminous efficiency and a novel arylamine compound which realizes the same.
