Abstract
The present invention provides an organic light emitting device including a compound and an organic material layer composed of one more layers including a first electrode, a second electrode and a light emitting layer disposed between the first electrode and the second electrode, in which one or more layers of the organic material layer include the compound of Formula 1 or a compound in which a heat curable or photo curable functional group is introduced into the above-described compound.
Claims18
A dibenzofuran-based compound represented by the following Formula 1:
- Wherein L1 is an arylene group having 6 to 40 carbon atoms;

- R2 and R3 are the same as each other, and are each an aryl group having 10 to 16 ring-membered carbon atoms, which is unsubstituted or substituted with one or more substituents selected from the group consisting of an alkyl group having 1 to 20 carbon atoms, an alkenyl group having 2 to 20 carbon atoms, an alkoxy group having 1 to 20 carbon atoms, a fluorenyl group, a carbazole group, a nitrile group, a thiophene group unsubstituted or substituted with a phenyl group, a benzothiophene group and a nitro group;
- a carbazole group unsubstituted or substituted with one or more substituents selected from the group consisting of an alkyl group having 1 to 20 carbon atoms, an alkenyl group having 2 to 20 carbon atoms, an alkoxy group having 1 to 20 carbon atoms, a fluorenyl group, a carbazole group, a nitrile group, a thiophene group unsubstituted or substituted with a phenyl group, a benzothiophene group and a nitro group;
- a thiophenyl group unsubstituted or unsubstituted with one or more substituents selected from the group consisting of an alkyl group having 1 to 20 carbon atoms, an alkenyl group having 2 to 20 carbon atoms, an alkoxy group having 1 to 20 carbon atoms, a fluorenyl group, a carbazole group, a nitrile group, a thiophene group unsubstituted or substituted with a phenyl group, a benzothiophene group and a nitro group;
- or a heterocyclic group including one or more of N, S and O atoms and having 5 to 12 ring-membered carbon atoms, which is unsubstituted or substituted with one or more substituents selected from the group consisting of an alkyl group having 1 to 20 carbon atoms, an alkenyl group having 2 to 20 carbon atoms, an alkoxy group having 1 to 20 carbon atoms, a fluorenyl group, a carbazole group, a nitrile group, a thiophene group unsubstituted or substituted with a phenyl group, a benzothiophene group and a nitro group,
- R4 is hydrogen;
- an alkyl group having 1 to 20 carbon atoms;
- or an alkoxy group having 1 to 20 carbon atoms, and may form an aliphatic, aromatic or hetero condensed ring with an adjacent group, and
- n means the number of substituents and is an integer of 1 to 6.
