Abstract
The present invention provides a novel organic compound, a material comprising the same for organic electroluminescence devices, and an organic electroluminescence device comprising the material. The organic compound provided in the present invention is useful in organic electroluminescence devices as a hole injection layer material, a hole transport layer material, an electron blocking layer material, and an emission layer material such as green and red phosphorescent host material, and can reduce the drive voltage, and increase the luminous efficiency, luminance, thermal stability, color purity and service life of the devices.
