SPYRO-TYPED ORGANIC MATERIAL AND ORGANIC ELECTROLUMINESCENT DEVICE UTILIZING THE SAME

摘要

The present invention relates to a spiro-type organic material and an organic electroluminescent device using the same. A first aspect provides a compound represented by chemical compound A. A second aspect provides a light-emitting host for the organic electroluminescent device containing the compound according to the first aspect of the present invention or a composition containing a dopant. A third aspect provides a positive electrode, a negative electrode and an organic layer containing the compound according to the first aspect of the present invention between both electrodes. The organic electroluminescent device of the present invention can obtain short-wavelength luminescence at high efficiency and has an improved lifespan property.
