Patent ID: 7629060

Claim:
An organic electroluminescent element comprising an anode, a cathode and a component layer including a light emission layer, the component layer being provided between the anode and the cathode, wherein the component layer contains a compound represented by formula 1, X 1 -(A 1 ) n Formula 1 wherein A 1 represents a group represented by formula 2, provided that plural A 1 may be the same or different, wherein Ar 1 represents a divalent aromatic hydrocarbon or aromatic heterocyclic group; R 1 and R 2 independently represent a hydrogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted cycloalkyl group, a substituted or unsubstituted aralkyl group, a substituted or unsubstituted aryl group, a substituted or unsubstituted alkoxy group, a substituted or unsubstituted aryloxy group, a cyano group, a hydroxyl group, a substituted or unsubstituted alkenyl group, or a halogen atom; na and nb independently represent an integer of from 1 to 4; and X 1 represents a group represented by formula (d), (e), (f), (h), (i), (j), or (k), wherein R 41 and R 42 independently represent an alkyl group, provided that the total carbon atom number of the alkyl group is from 3 to 9; R 51 and R 52 independently represent a substituted or unsubstituted alkyl group, a substituted or unsubstituted cycloalkyl group, a substituted or unsubstituted aralkyl group, a substituted or unsubstituted aryl group, a substituted or unsubstituted alkoxy group, a substituted or unsubstituted aryloxy group, a cyano group, a hydroxyl group, a substituted or unsubstituted alkenyl group, or a halogen atom; R 61 represents an alkyl group; R 71 through R 78 independently represent a hydrogen atom, an alkyl group, or an alkoxy group; R 81 through R 88 independently represent a hydrogen atom, an alkyl group, or an alkoxy group; R 91 through R 98 independently represent a hydrogen atom, an alkyl group, or an alkoxy group; and “*” represents a linkage site, provided that when X 1 represents formula (d), (e), or (f), n is 2, and when X 1 represents formula (h), (i), (j), or (k), n is 4.
