Light-emitting material comprising photoactive group-bonded polysilsesquioxane having a ladder structure, thin film using the same and organic electronic device comprising the same

摘要

Disclosed is a light-emitting material including a polysilsesquioxane having a ladder structure with photoactive groups bonded to a siloxane backbone. In addition to superior heat resistance and mechanical property, the light-emitting material provides improved cotability and film property when prepared into a thin film. Further, it provides higher luminous efficiency than the existing organic-based light-emitting material.
