Claims16
An organic electroluminescent device comprising:
- a first electrode;
- a second electrode;
- and a light-emitting layer positioned between the first electrode and the second electrode, wherein the light-emitting layer comprises a host and a dopant, wherein the host comprises a compound represented by the following Formula 1, and wherein the dopant comprises a compound containing a boron (B) atom:
- wherein,
- an adjacent pair(s) in X15 to X18 is(are) liked to in the following Formula 1-A:
- wherein,
- X11 to X14, X15 to X18 that are not linked to form a ring(s), and X19 to X22 each independently represent hydrogen, deuterium, a substituted or unsubstituted (C6-C30)alkyl, a substituted or unsubstituted (C6-C30)cycloalkyl, a substituted or unsubstituted (C6-C30)aryl, a substituted or unsubstituted (3- to 30-membered)heteroaryl, or a combination thereof;
- L11 and L12 each independently represent a single bond or a substituted or unsubstituted (C6-C30)arylene;
- and
- Ar11 and Ar12 each independently represent a substituted or unsubstituted (C6-C30)aryl, a substituted or unsubstituted (3- to 30-membered)heteroaryl having hole-transporting properties, or a combination thereof.
