Compound and application thereof, and organic electroluminescent device comprising compound

The invention relates to a compound and application thereof, and an organic electroluminescent device comprising the compound, wherein the compound has a structure shown as a formula (I). According tothe invention, the parent nucleus of the compound provided by the invention is formed by fusing carbazole and an aromatic ring or an aromatic heterocyclic ring, so that the ET of the compound is slightly reduced due to the expansion of the conjugated system, and the injection barrier of charges is reduced so as to make the molecule provided by the invention have lower voltage and higher efficiency; and quinazoline and triazine are matched to serve as electron withdrawing groups, so that carrier transmission in the device is relatively balanced, efficiency roll-off is not easy to cause, the efficiency of the device is obviously improved, and the service life of the device is obviously prolonged.

NOVEL ORGANIC ELECTROLUMINESCENT COMPOUNDS AND ORGANIC ELECTROLUMINESCENT DEVICE USING THE SAME

Provided are novel organic electroluminescent compounds and an organic electroluminescent device using the same. Because the organic electroluminescent compound disclosed herein exhibits good luminous efficiency and an excellent life performance, it may be used to manufacture OLED devices very superior in terms of operating life and which consume less power due to improved power efficiency.
