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.
