    摘要: PROBLEM TO BE SOLVED: To provide an organic EL element having a hole transport layer which is excellent in emission stability during driving at a high temperature.SOLUTION: There is provided a tetramine compound represented by the following general formula (1): (where, R1, R2 and R3 may be the same or different and represent a hydrogen atom, a tertiary alkyl group having 4 to 8 carbon atoms, an unsubstituted aryl group or an aryl group substituted with a tertial alkyl group having 4 to 8 carbon atoms; n represents 3 or 4). The present invention can provide a material suitable for an organic EL element requiring emission stability during driving at a high temperature, which is the biggest problem of the conventional organic EL element. In addition, there is disclosed a method for producing an organic EL element containing the tetramine compound and the tetramine compound.
