Claims20
An organic electroluminescence device comprising:
- a first electrode;
- a second electrode facing the first electrode;
- and
- an emission layer between the first electrode and the second electrode,
- wherein the first electrode and the second electrode each independently comprise Ag, Mg Cu, Al, Pt, Pd, Au, Ni, Nd, Ir, Cr, Li, Ca, LiF/Ca, LiF/Al, Mo, Ti, In, Zn, Sn, a compound thereof, a mixture thereof, or a oxide thereof,
- wherein the emission layer comprises a condensed polycyclic compound represented by Formula 1:
- wherein, in Formula 1,
- W1 to W6 are each independently CR1 or a carbon atom connected to a substituent represented by Formula 2;
- R1 is a hydrogen atom, a deuterium atom, a halogen atom, a substituted or unsubstituted amine group, a substituted or unsubstituted alkyl group having 1 to 20 carbon atoms, a substituted or unsubstituted aryl group having 6 to 30 ring-forming carbon atoms, or a substituted or unsubstituted heteroaryl group having 2 to 30 ring-forming carbon atoms, and/or is bonded to an adjacent ring to form a ring;
- at least two adjacent positions among W1 to W6 are carbon atoms connected to the substituent represented by Formula 2;
- and
- two or three of the substituent represented by Formula 2 are connected to Formula 1;
- wherein, in Formula 2,
- X1 is O, S, or NAr1;
- Ar1 is a substituted or unsubstituted aryl group having 6 to 30 ring-forming carbon atoms, or a substituted or unsubstituted heteroaryl group having 2 to 30 ring-forming carbon atoms, or is bonded to an adjacent group to form a ring;
- R2 to R4 are each independently a hydrogen atom, a deuterium atom, a halogen atom, a substituted or unsubstituted amine group, a substituted or unsubstituted alkyl group having 1 to 20 carbon atoms, a substituted or unsubstituted aryl group having 6 to 30 ring-forming carbon atoms, or a substituted or unsubstituted heteroaryl group having 2 to 30 ring-forming carbon atoms, and/or are bonded to an adjacent ring to form a ring;
- a and b are each independently an integer of 0 to 3;
- and
- c is an integer of 0 to 4.
