ABSTRACT:
Materials for organic electroluminescence devices represented by following general formula [1]:wherein A represents a substituted or unsubstituted arylene group having 22 to 60 carbon atoms, X1to X4each independently represent a substituted or unsubstituted arylene group having 6 to 30 carbon atoms, X1and X2may be bonded to each other, X3and X4may be bonded to each other, Y1to Y4each independently represent an organic group represented by general formula [2], a to d each represent an integer of 0 to 2 and, when the arylene group represented by A has 26 or less carbon atoms, a+b+c+d>0 and the arylene group does not contain two or more anthracene nucleus;general formula [2] being:wherein R1to R4each independently represent 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 R1and R2or R3and R4, Z represents a substituted or unsubstituted aryl group having 6 to 20 carbon atoms and n represents 0 or 1.
