ABSTRACT:
A material for organic electroluminescence devices of the invention which is for use in combination with at least one phosphorescent metal complex has a specific heterocyclic structure. The material for organic electroluminescence devices is used as a host material or a hole transporting material. An organic electroluminescence device having an anode, a cathode and an organic thin film layer having one or more layers which is interposed between the anode and cathode, in which at least one layer of the organic thin film layer contains the material for organic electroluminescence devices, has a high emitting efficiency, causes little pixel defects, is excellent in heat resistance, and shows a long lifetime.
