    • 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.
    • 提供一种用于低电压且显着提高驱动稳定性的高发光效率的有机电致发光器件(有机EL器件)的空穴注入材料和使用该材料的有机EL器件。 用于有机EL器件的空穴注入材料选自苯六羧酸酐,苯六羧酸酰亚胺或N-取代苯六羧酸酰亚胺。 此外,有机EL器件具有至少一个发光层和在彼此相对布置的阳极和阴极之间的至少一个空穴注入层,并且包括上述用于有机EL器件的空穴注入材料 空穴注入层。 有机EL器件可以在空穴注入层或与空穴注入层相邻的层中含有电离电位(IP)为6.0eV以下的空穴传输材料。
