- ORGANIC COMPOUNDS AND ORGANIC ELECTRO LUMINESCENCE DEVICE COMPRISING THE SAME
-
The present invention relates to a novel organic compound and an organic electroluminescent device comprising the same. The organic electroluminescent device with improved luminous efficiency, driving voltage, and service life can be provided by introducing a light emitting layer using a triazolebiscarbazole-based compound as a host material to the organic electroluminescent device.

- Efficient Synthesis of Conjugated 1,3,4-Thiadiazole Hybrids through Palladium-Catalyzed Cross-Coupling of 2,5-Bis(4-bromophenyl)-1,3,4-thiadiazole with Boronic Acids
-
New derivatives of 2,5-bis(4-heteroarylphenyl)-1,3,4-thiadiazole were synthesized under Suzuki cross-coupling reactions from 2,5-bis(4-bromophenyl)-1,3,4-thiadiazole and commercially available boronic acids. Reactions were conducted in a two-phase solvent
