    摘要： This invention provides an organic electroluminescent element (organic EL element) utilizing phosphorescence which emits light efficiently with high luminance at low current density, shows good driving stability and is applicable to display devices such as flat panel displays and illuminating devices. The element comprises an anode, organic layers and a cathode piled one upon another on a substrate, at least one of the organic layers is a light-emitting layer containing a host material and a dopant material and a pyrazole-derived compound having 2-4 pyrazole structures represented by the following formula I in the same molecule is used as said host material; wherein, Ar1-Ar3 are independently hydrogen or substituted or unsubstituted aromatic hydrocarbon groups and at least one of Ar1-Ar3 is a group other than hydrogen.

    摘要： This invention relates to an organic electroluminescent element comprising a substrate, an anode, an organic layer and a cathode placed in layer one upon another; at least one layer in the organic layer is a luminescent layer comprising a host agent and a doping agent and an azole compound having an oxadiazole structure and a triazole structure in its molecule is used in at least one layer in the organic layer. This azole compound is used as a host agent in the luminescent layer and it can also be used in a hole blocking layer or electron transporting layer. This organic EL element is suitable for use in full-color and multicolor panels and shows a higher luminous efficiency and better driving stability than EL elements utilizing the luminescence from the singlet state.
