POLYMERIC AMBIPOLAR HOSTS FOR PHOSPHORESCENT GUEST EMITTERS

摘要

The inventions describe disclosed and described herein relate to polymeric ambipolar host materials for guest phosphorescent metal complexes which together can form emission layers of organic light emitting diodes (OLEDs). Methods of making the ambipolar polymers or copolymers from novel monomeric ambipolar materials are also described, as are unexpectedly efficient OLED devices containing the materials of the inventions.
