Classification: CPC H  C  G | IPC C  H

Claim 10:
11. The organic electroluminescence device according to claim 8, wherein the compound represented by the formula (11) is represented by the following formula (12),, wherein in the formula (12), an atomic bonding * is bonded to one of R72 to R79; L101 and Ar101 are as defined in the formula (11);
R101A to R108A are independently a hydrogen atom, or a substituted or unsubstituted aryl group including 6 to 50 ring carbon atoms;
X11 is O, S, or N(R71);
R71 is a hydrogen atom, a substituted or unsubstituted alkyl group including 1 to 50 carbon atoms, or a substituted or unsubstituted aryl group including 6 to 50 ring carbon atoms;
one of R72 to R79 is an atomic bonding that is bonded to L101;
one or more pair of two or more adjacent among R72 to R79 that are not bonded to L101 may form a substituted or unsubstituted, saturated or unsaturated ring;
R72 to R79 that are not bonded to L101 and do not form the substituted or unsubstituted, saturated or unsaturated ring are independently a hydrogen atom, a substituted or unsubstituted alkyl group including 1 to 50 carbon atoms, or a substituted or unsubstituted aryl group including 6 to 50 ring carbon atoms.
