ABSTRACT:
Disclosed are a monomer of iridium complex having a fluoro group as a functional group, a monomer of carbazole derivative having a hydroxy group as the functional group, and a copolymer containing the monomers in its main chain. The iridium complex used as a phosphorescent material and the carbazole derivative having an excellent hole transporting capability are synthesized as the monomer to form the copolymer. The content of iridium complex is easily controlled, and the carbazole derivative and iridium complex are contained in the main chain during the copolymer formation, thereby capable of manufacturing a light emitting device with higher heat resistance and chemical stability.
