The present invention provides a compound of formula (I) for an organic electroluminescent device:
wherein X and Y are each independently selected for the group consisting of an alkyl substituted, aryl substituted or unsubstituted carbazole, indolocarbazole, triphenylsilyl and diphenylphosphine oxide represented by formula (A), (B), (C), (D) or (E),
in which R
1
, R
2
, and R
3
are each independently selected from the group consisting of a hydrogen, an alkyl having 1 to 15 carbons atoms, an aryl group having 6 to 15 carbons atoms, an alkyl substituted, an aryl substituted or unsubstituted triphenylsilyl, and a diphenylphosphine oxide represented by the formula (D) or (E); m and n are each independently 0 or 1, provided that m+n is 1 or more; and Ar
1
and Ar
2
are each independently selected from the group consisting of an alkyl substituted, aryl substituted or unsubstituted phenyl, tolyl, naphthyl, fluorenyl, anthracenyl, and phenanthryl.
