摘要:
An electroluminescent cell which exhibits a high luminous efficiency and excellent durability is provided. The electroluminescent material comprises a unit (AB) which is formed by alternate copolymerization of hole transfer monomers and electron transfer monomers, and a unit (A) which is formed by the polymerization of hole transfer monomers, wherein the molar ratio of the total of the structural units originating from the hole transfer monomers and the structural units originating from the electron transfer monomers in the unit (AB) and the structural units originating from the hole transfer monomers in the unit (A) is from 50:50 to 5:95. The electroluminescent cell has an anode layer 2, an electroluminescent material layer 3 made from the electroluminescent material, an electron transfer luminous layer 4, and a cathode layer 5.
