Abstract:
A composition contains an organic compound and an anthracene compound different from the organic compound, the anthracene compound having a hydrogen atom at at least one of positions 9 and 10, in which the concentration of the anthracene compound is 100 ppm or less. Additionally, a long-lived organic light-emitting device includes an organic compound layer containing a reduced concentration of the anthracene compound.
