The invention discloses a pyridoindole compound and an organic light-emitting device thereof. The general formula of the pyridoindole derivatives is: Among them, L is selected from substituted or unsubstituted C 6 -C 60 aryl groups, substituted or unsubstituted C 5 -C 60 fused ring groups and heterocyclic groups; R 1 -R 2 are selected from hydrogen atoms, substituted or unsubstituted C 1 -C 30 alkyl, substituted or unsubstituted C 1 -C 60 alkoxy, substituted or unsubstituted C 6 -C 60 aryl, substituted or unsubstituted C 5 -C 60 heterocyclic group and fused ring group; X 1 to X 4 are selected from nitrogen or carbon. The device prepared by the pyridoindole derivative of the present invention has high luminous efficiency. |
