Claim 16:
17. The organic electroluminescence device according to claim 8, wherein the compound represented by the formula (11) is represented by the following formula (12A):, wherein in formula (12A), the atomic bonding * is bonded to one of R72A to R79A;
L101 and Ar101 are as defined in the formula (11);
R101A to R108A are independently a hydrogen atom, 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 or more pair of two or more adjacent among R72A to R79A may form a substituted or unsubstituted, saturated or unsaturated ring, and two adjacent among R72A to R79A form a ring represented by the following formula (12A-1);
R72A to R79A that do not form a 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:, wherein in the formula (12A-1), each of the two atomic bondings * are bonded to two adjacent among R72A to R79A;
one of R80 to R83 is an atomic bonding that is bonded to L101;
R80 to R83 that are not bonded to L101 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.
