Document Type and Number:
Japanese Patent JP5216293
Kind Code:
B2
Abstract:
To provide a novel bipolar organic compound, in particular a highly heat resistant bipolar organic compound, an electrochemically stable bipolar organic compound, a light emitting element and a light emitting apparatus with low electricity consumption that require a low drive voltage, and a light emitting element and a light emitting apparatus made to have excellent heat stability and a long life by using the bipolar organic compound.
A quinoxaline derivative such as (2,3-bis[4-(4-diphenylaminophenyl)phenyl]quinoxaline (acronym:TPAPQ)) is disclosed.
