Abstract:
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.
