摘要:
Provided are a hole-injecting material for an organic electroluminescent device (organic EL device) exhibiting high luminous efficiency at a low voltage and having greatly improved driving stability, and an organic EL device using the material. The hole-injecting material for an organic EL device is selected from benzenehexacarboxylic acid anhydrides, benzenehexacarboxylic acid imides, or N-substituted benzenehexacarboxylic acid imides. Further, the organic EL device has at least one light-emitting layer and at least one hole-injecting layer between an anode and a cathode arranged opposite to each other, and includes the above-mentioned hole-injecting material for an organic EL device in the hole-injecting layer. The organic EL device may contain a hole-transporting material having an ionization potential (IP) of 6.0 eV or less in the hole-injecting layer or a layer adjacent to the hole-injecting layer.
