A 3,6-diphenylcarbazole compound, which has a specific formula and realizes an organic electroluminescent device having high durability and high luminous efficiency. An electroluminescent device which includes an anode; a cathode which faces the anode; and at least one layer including a luminescent layer, optionally a hole transporting layer and an electron transporting layer, which is located between the anode and the cathode, wherein the at least one layer includes the 3,6-diphenylcarbazole compound.
The present invention relates to organic electroluminescent devices which comprise mixtures of at least two electron-conducting materials, in particular as matrix for phosphorescent emitters.
