    摘要： The present invention provides a tetramine compound represented by the following general formula (1): wherein R1, R2 and R3, which may be the same or different, each represents a hydrogen atom, a tertiary alkyl group having 4 to 8 carbon atoms, an unsubstituted aryl group or an aryl group substituted with a tertiary alkyl group having 4 to 8 carbon atoms, and n represents 3 or 4. According to the invention, there can be provided a material suitable as a material for an organic EL element requiring luminous stability at the time of high temperature driving which has been the largest problem of the conventional organic EL element. Further, an organic EL element containing the above-mentioned tetramine compound and a method for producing the above-mentioned tetramine compound are also disclosed.
