<p>PURPOSE: A triphenylene based compound with improved glass transition temperature and thermal stability and an organic electroluminescent device using the same are provided to enhance brightness, power efficiency, heat resistance, hole or electrotransport, and injection performance. CONSTITUTION: An organic electroluminescent device is represented by chemical formula 1 or 2. Here, X and Y are NR15 or a single bond, R1-R15 are respectively selected from hydrogen, deuterium, halogen, amino, nitro, nitrile, C1-40 alkyl, C2-40 alkenyl, C2-40 alkynyl, C5-40 aryl, C1-40 heteroaryl, C1-40 alkoxy, C5-40 aryloxy, C1-40 alkyl amino, C5-40 arylamino, C5-40 diarylamino, C5-40 heteroarylamino, C2-40 diheteroarylamino, C6-40 arylalkyl, C6-40 heteroarylalkyl, C3-40 cycloalkyl, C1-40 halogen alkyl, C3-40 heterocycloalkyl, C3-40 alkylsilyl, C3-40 arylsilyl and C3-40 heteroaryl silyl.</p> |
