Abstract: A heterocyclic compound represented by Chemical Formula 1, a light-emitting device that includes the heterocyclic compound, and an electronic device that includes the light-emitting device are provided. The light-emitting device includes a first electrode, a second electrode, and an intermediate layer disposed between the first electrode and the second electrode. The intermediate layer includes the heterocyclic compound. The variables in Chemical Formula 1 are as defined herein.

Abstract: Provided are novel compounds in accordance with Formula I for an organic electronic material and an organic electroluminescent device using same. The compound for an organic electronic material disclosed herein exhibits high electron transport efficiency and thus prevents crystallization upon manufacturing a device, and also facilitates the formation of a layer, thus improving current properties of the device. Thereby, OLED devices having improved power efficiency as well as reduced operating voltage can be manufactured.
