Patent ID: 7892658

Claim:
An organic light emitting device, comprising: a first electrode; organic material layer(s) comprising a light emitting layer, wherein at least one layer of the organic material layer(s) includes the compound of Formula 1; and a second electrode; wherein the first electrode, the organic material layer(s), and the second electrode form layered structure, wherein X is C or Si; A is NZ1Z2; B is NZ3Z4; Y is a bond; bivalent aromatic hydrocarbons; bivalent aromatic hydrocarbons which are substituted with at least one substituent group selected from the group consisting of nitro, nitrile, halogen, alkyl, alkoxy, and amino groups; a bivalent heterocyclic group; or a bivalent heterocyclic group which is substituted with at least one substituent group selected from the group consisting of nitro, nitrile, halogen, alkyl, alkoxy, and amino groups; Z1 to Z4 are each independently hydrogen; aliphatic hydrocarbons having a carbon number of 1-20; aromatic hydrocarbons; aromatic hydrocarbons which are substituted with at least one substituent group selected from the group consisting of nitro, nitrile, halogen, alkyl, alkoxy, amino, aromatic hydrocarbon, and heterocyclic groups; a silicon group substituted with aromatic hydrocarbons; a heterocyclic group; a heterocyclic group which is substituted with at least one substituent group selected from the group consisting of nitro, nitrile, halogen, alkyl, alkoxy, amino, aromatic hydrocarbon, and heterocyclic groups; a thiophenyl group which is substituted with hydrocarbons having a carbon number of 1-20 or aromatic hydrocarbons having a carbon number of 6-20; or a boron group which is substituted with aromatic hydrocarbons; R1 to R11 are each independently hydrogen, a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkoxy group, a substituted or unsubstituted alkenyl group, a substituted or unsubstituted aryl group, a substituted or unsubstituted arylamine group, a substituted or unsubstituted heterocyclic group, an amino group, a nitrile group, a nitro group, a halogen group, an amide group, or an ester group, and R1 to R11 may form aliphatic or hetero condensation rings along with adjacent groups; and R7 and R8 may be directly connected to each other, or may form a condensation ring along with a group selected from the group consisting of O, S, NR, PR, C═O, CRR′, and SiRR′, wherein R and R′ are each independently or collectively are hydrogen, a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkoxy group, a substituted or unsubstituted alkenyl group, a substituted or unsubstituted aryl group, a substituted or unsubstituted arylamine group, a substituted or unsubstituted heterocyclic group, a nitrile group, an amide group, or an ester group, and may form a condensation ring to form a spiro compound.
