Abstract
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.
