NOVEL ORGANIC ELECTROLUMINESCENT COMPOUNDS AND ORGANIC ELECTROLUMINESCENT DEVICE COMPRISING THE SAME

摘要

The present invention relates to a novel organic electroluminescent compound and an organic electroluminescent device comprising the same. The organic electroluminescent compound according to the present invention has high electron transport efficiency, which can prevent crystallization during the formation of the device; is effective in forming a layer(s) to improve the current property of the device, and thus reduces the driving voltage of the device; and has the advantages of providing an OLED device having advanced power efficiency. While organic electroluminescent devices comprising conventional organic electroluminescent compounds need hole blocking layers, the organic electroluminescent device comprising the organic electroluminescent compound of the present invention does not have to comprise a hole blocking layer, and thus can decrease the voltage needs of the device.
