NOVEL ORGANIC ELECTROLUMINESCENT COMPOUNDS AND ORGANIC ELECTROLUMINESCENT DEVICE USING THE SAME

摘要

PURPOSE: An organic electroluminescent compound is provided to form an organic electroluminescent device with the improved driving durability and efficiency using the organic electroluminescent compound with the excellent lifetime property. CONSTITUTION: An organic electroluminescent compound includes a structure marked with chemical formula 1. In the chemical formula 1, L is a substituent of a compound marked with chemical formula 2. A ring refers to a monocyclic or polycyclic aromatic ring, and B ring refers to anthracene. The organic electroluminescent compound is formed with a first electrode, a second electrode, and an organic material layer inserted in between the first and the second electrodes. The organic material layer includes more than one dopant material.
