Abstract

According to the present invention, there are provided an indenoindole derivative represented by the following general formula (1); and an organic electroluminescent element including a pair of electrodes and at least one organic layer sandwiched therebetween, wherein the above compound is used as a constituent material for the at least one organic layer. The indenoindole derivative of the present invention provides an organic compound, which is excellent in hole injection/transport performance, has electron blocking capability, is highly stable in a thin film state, and excels in heat resistance, as a material for a high efficiency, high durability organic electroluminescent element. An organic electroluminescent element formed using this compound is highly efficient and highly durable.
