Abstract
The present disclosure relates to an organic electroluminescent compound and an organic electroluminescent device comprising the same. The organic electroluminescent compound of the present disclosure has a high glass transition temperature that can be used in a deposition process. In addition, an organic electroluminescent device having low driving voltage, a high luminous efficiency and/or long lifespan characteristic can be provided with the use of the organic electroluminescent compound according to the present disclosure.
Claims9
An organic electroluminescent compound represented by the following formula 1:
- wherein formula 1,
- Z1 to Z11 each independently represent CR1 or N;
- R1 represents hydrogen, deuterium, halogen, a substituted or unsubstituted (C1-C30)alkyl, a substituted or unsubstituted (C6-C30)aryl, a substituted or unsubstituted (5- to 30-membered)heteroaryl, a substituted or unsubstituted (3- to 7-membered)heterocycloalkyl, or a substituted or unsubstituted (C3-C30)cycloalkyl;
- or may be linked to an adjacent substituent to form a substituted or unsubstituted, (C3-C30) mono- or polycyclic, alicyclic or aromatic ring, or a combination of alicyclic and aromatic rings, whose carbon atom may be replaced with at least one heteroatom selected from nitrogen, oxygen, and sulfur;
- L represents a single bond, a substituted or unsubstituted (C6-C30)arylene, or a substituted or unsubstituted (5- to 30-membered)heteroarylene;
- Ar represents hydrogen, deuterium, halogen, a substituted or unsubstituted (C1-C30)alkyl, a substituted or unsubstituted (C6-C30)aryl, a substituted or unsubstituted (5- to 30-membered)heteroaryl, a substituted or unsubstituted (C3-C30)cycloalkyl, a substituted or unsubstituted (3- to 7-membered)heterocycloalkyl, a substituted or unsubstituted (C6-C30)ar(C1-C30)alkyl, —N(R11)(R12), —Si(R13)(R14)(R15), —S(R16), —O(R17), cyano, nitro or hydroxy;
- R11 to R17 each independently represent hydrogen, deuterium, halogen, a substituted or unsubstituted (C1-C30)alkyl, a substituted or unsubstituted (C6-C30)aryl, a substituted or unsubstituted (5- to 30-membered)heteroaryl, a substituted or unsubstituted (3- to 7-membered)heterocycloalkyl, or a substituted or unsubstituted (C3-C30)cycloalkyl;
- or may be linked to an adjacent substituent to form a substituted or unsubstituted, (C3-C30) mono- or polycyclic, alicyclic or aromatic ring, or a combination of alicyclic and aromatic rings, whose carbon atom may be replaced with at least one heteroatom selected from nitrogen, oxygen, and sulfur;
- the heteroaryl(ene) contains at least one heteroatom selected from B, N, O, S, Si, and P.
