Abstract
The present invention relates to electronic devices comprising an organic compound acting to inject or transport holes with p-type semi-conducting characteristics. The present invention provides for electronic devices comprising at least one or more layers selected from a group composed of a hole injecting layer, a hole transporting layer, and a hole injecting and transporting layer which comprises hexaazatriphenylene based organic compound represented by chemical formula (1), wherein the devices can use low drive-voltage, and can improve a light-emitting life.
Claims31
An organic light-emitting device comprising at least one or more layers interposed between an anode and a cathode, wherein the one or more layers comprise an organic compound represented by Chemical Formula 1:
- wherein, each R is independently or simultaneously selected from the group consisting of hydrogen atom, C1-C12 hydrocarbon, halogen, alkoxy, arylamine, ester, amide, aromatic hydrocarbon, heterocyclic compound, nitro, and nitrile (—CN) group, and
- wherein the organic compound represented by the Chemical Formula 1 is a p-type organic semiconductor.
An electronic device comprising at least one or more layers selected from a group consisting of a hole-injecting layer, a hole-transporting layer, and a hole-injecting-and-transporting layer, wherein the one or more layers comprise an organic compound represented by the Chemical Formula 1:
