Patent ID: 11925115
Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Organic fine chemistry (Chemistry)
Classification: CPC H  C | IPC C  H

Claim 0:
1. An organic light-emitting device comprising:
a first electrode;
a second electrode; and
an organic layer disposed between the first electrode and the second electrode and comprising an emission layer,
wherein the emission layer comprises a compound satisfying Conditions 5′ and 6 below:

0 eV<ΔEST≤0.1 eV  <Condition 5′>

ΔEST>0.2 eV  <Condition 6>

wherein, in Conditions 5′ and 6, ΔEST2 indicates the value obtained by subtracting a 2nd-lowest triplet excitation energy level calculated for a T2 equilibrium structure of the compound from a lowest singlet excitation energy level calculated for an S1 equilibrium structure of the compound and ΔEST indicates the value obtained by subtracting a lowest triplet excitation energy level calculated for a T1 equilibrium structure of the compound from a lowest singlet excitation energy level calculated for the S1 equilibrium structure of the compound.
