Organic electrolumescence device

A dopant material for an organic electroluminescence device represented by formula (4):

• wherein X1 to X4 each independently represent a substituted or unsubstituted arylene group having 6 to 30 carbon atoms, X1 and X2 may be bonded to each other, X3 and X4 may be bonded to each other, Y1 to Y4 each independently represent an organic group represented by formula (2), a to d each represent an integer of 0 to 2 with the proviso that a+b+c+d≧0;
• wherein R1 to R4 are each independently a hydrogen atom, a substituted or unsubstituted alkyl group having 1 to 20 carbon atoms, a substituted or unsubstituted aryl group having 6 to 20 carbon atoms, cyano group or form a triple bond by a linkage of R1 and R2 or R3 and R4, Z represents a substituted or unsubstituted aryl group having 6 to 20 carbon atoms, and n represents 0 or 1.
