NOVEL ORGANIC ELECTROLUMINESCENT COMPOUNDS AND ORGANIC ELECTROLUMINESCENT DEVICE USING THE SAME

摘要

The present invention relates to a novel organic electroluminescent compound and an organic electroluminescent device using the same and, more specifically, to an organic luminescent compound selected among chemical formula 1 to chemical formula 5. [In chemical formula 1 to chemical formula 5, X and Y are selected among N(Ar_1), O and S, respectively. Ar_1 is able to be different from each other, and when Ar_1 is plural, Ar_1 is indicated as Ar_1 or Ar_2. Z_1 to Z_8 are selected among C(Ar_3) and N, respectively. Ar_3 is able to be different from each other, and an adjacent Ar_3 is able to form a circle by a mutual combination.] The organic electroluminescent compound according to the present invention exhibits excellent luminance efficiency as compared to an existing host material by being used as a host material of an organic electroluminescent material in an OLED device and has excellent durability of materials, thereby being able to manufacture an OLED in which the driving durability of the device is excellent.
