Provided is a heterocyclic compound represented by Formula I: n nwherein Ar 1 is a linking group and a C6-C16 arylene or heteroarylene group; Ar 2 and Ar 3 are each independently a C6-C20 aryl group, a C4-C20 heteroaryl group or a C6-C20 fused polycyclic group; Ar 4 is a C6-C20 aryl group, a C6-C20 aryloxy group, a C4-C20 heteroaryl group or a C6-C20 fused polycyclic group; and Ar 1 and Ar 3 , or Ar 2 and Ar 3 may be connected to each other to form a ring. The heterocyclic compound has high electrical stability and excellent charge transporting capability, and thus can be efficiently used as a material for forming at least one of a hole injecting layer, a hole transporting layer and an emitting layer suitable for fluorescent and phosphorescent devices realizing all colors including red, green, blue and white. |
