ABSTRACT:
Objects of the invention are to provide a compound of a single molecular species having excellent hole injection/transport property suitable for highly efficient and highly durable organic EL device and excellent amorphousness, and provide a highly efficient and highly durable organic EL device using the compound. This invention relates to an arylamine compound having a molecular weight of 1,500 to 6,000 represented by the following general formula (1), and to an organic electroluminescence device having a pair of electrodes and at least one organic layer sandwiched therebetween, wherein the compound is used as a constituting material of the at least one organic layer:wherein X represents a single bond, CH or CH2, or N or NH; Ar1and Ar2are respectively the same and each represents a substituted or unsubstituted phenylene group, biphenylene group, or terphenylene group; R1, R2, R3, and R4each independently represents an aryl group, wherein the aryl group may be substituted by a diarylamine group in such a manner as to form a triphenylamine partial structure, and the aryl group at the terminal may be substituted, by repetition, by a diarylamino group in such a manner as to form a triphenylamine-like partial structure; m represents an integer of 0 to 2; and n represents 0 or 1.
