Disclosed are electroluminescent devices that comprise organic layers that contain triazine compounds. The triazine compounds are suitable components of blue-emitting, durable, organo-electroluminescent layers. The electroluminescent devices may be employed for full color display panels in, for example, mobile phones, televisions and personal computer screens.
