摘要:
A heterocyclic compound represented by a general Formula 1 and an organic light-emitting device including the heterocyclic compound. In some embodiments the heterocyclic compound of Formula 1 may be used as a light-emitting material, a hole transporting material, or an electron transporting material. The heterocyclic compound of Formula 1 having a heterocyclic group in the molecules thereof has a high glass transition temperature (Tg) or a high melting point due to the inclusion of the heterocyclic group. Thus, the heterocyclic compound has high heat resistance against Joule's heat generated in an organic layer, between organic layers, or between an organic layer and a metal electrode when light emission occurs, and has high durability in high-temperature environments. An organic light-emitting device manufactured using the heterocyclic compound of Formula 1 has high durability when stored or operated. In addition, due to the inclusion of a substituent such as an aryl group or heteroaryl group, molecular layers formed as thin films may be maintained in good condition, thereby improving the characteristics of the organic light-emitting device.

A heterocyclic compound represented by one of Formulae 1-4 below and an organic light-emitting device including an organic layer that includes the heterocyclic compound. The heterocyclic compounds have excellent light-emitting characteristics and excellent electron transporting characteristics, and thus may be used as electron injecting materials or electron transporting materials suitable for all-color fluorescent and phosphorescent devices, such as red, green, blue, and white fluorescent and phosphorescent devices. In particular, the heterocyclic compounds are efficiently used as light-emitting materials of green, blue, and while fluorescent devices. By using the heterocyclic compounds, organic light-emitting devices having high efficiency, low driving voltage, high brightness, and long lifespan may be prepared.
摘要:
A heterocyclic compound of formula 1 and an organic light-emitting device including an organic layer containing the heterocyclic compound. The heterocyclic compound of Formula 1 may be suitable as a material for an emission layer, an electron transport layer or an electron injection layer of an organic light-emitting device. Due to the inclusion of the heterocylic group in its molecular structure, the heterocyclic compound of Formula 1 may have a high glass transition temperature (Tg) or a high melting point, and may prevent crystallization. An organic light-emitting device manufactured using the heterocyclic compound of Formula 1, in which a chrysene group and an indole group are fused, has excellent durability when stored or operated.
