Patent ID: 11968891
Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Organic fine chemistry (Chemistry)
Classification: CPC H  C | IPC C  H

Claim 0:
1. An organic electroluminescence device, comprising:
a first electrode;
a hole transport region on the first electrode;
an emission layer on the hole transport region;
an electron transport region on the emission layer; and
a second electrode on the electron transport region,
wherein:
the emission layer includes a heterocyclic compound that includes a nitrogen-containing monocycle, at least one linker, and two or more carbazole moieties,
the at least one linker is a substituted or unsubstituted dibenzofuran group or a substituted or unsubstituted dibenzothiophene group,
at least one of the carbazole moieties and the nitrogen-containing monocycle are bonded to the at least one linker in an ortho relationship to one of the six-membered rings of the dibenzofuran group of the substituted or unsubstituted dibenzofuran group or the dibenzothiophene group of the substituted or unsubstituted dibenzothiophene group, and
the other of the six-membered rings of the dibenzofuran group of the substituted or unsubstituted dibenzofuran group or the dibenzothiophene group of the substituted or unsubstituted dibenzothiophene group is not substituted with a heteroaryl group.
