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.

Synthesis of 1,3,4-thiadiazoles from aldehyde hydrazones

Reaction of p-tolualdehyde hydrazone with disulfur dichloride in the presence of DBU gave 2,5-di (p-tolyl)-1,3,4-thiadiazole (1a) in 54% yield. Phenyldiazomethane also reacted with disulfur dichloride to afford 2,5-diphenyl-1,3,4-thiadiazole (1b) in 80% y
