The present disclosure relates to compounds capable of emitting delayed fluorescence, and uses of the compounds in organic light-emitting diodes.

Composition of matter for use in organic light-emitting diodes

An organic light-emitting device having an organic mixed layer that contains a first organic compound and a second organic compound and a third organic compound satisfying E(A)>E(B)>E(C). E(A), E(B) and E(C) each represent a lowest excited singlet energy level of the first organic compound, the second organic compound and the third organic compound, respectively. The second organic compound and the third organic compound are delayed fluorescent materials. The invention provides an organic light-emitting device having a long lifetime and a high light emission efficiency.

Organic light emitting element

An organic light emitting element produced by using a light emitting composition that contains both a first compound having a PBHT value more than 0.730 and a second compound having Elower than that of the first compound and ΔEless than 0.20 eV is excellent in durability. Eis the lowest excited singlet energy level, ΔEis the difference between the lowest excited singlet energy level and the lowest excited triplet energy level.
