Claim 7:
8. The organic electroluminescence device according to claim 7, wherein the emitting layer further comprises a compound represented by the following formula (11):, wherein in the formula (11), except for the case where R101 to R110 that forms a ring, as described later, R101 to R110 are independently a hydrogen atom, a substituted or unsubstituted alkyl group including 1 to 50 carbon atoms, a substituted or unsubstituted alkenyl group including 2 to 50 carbon atoms, a substituted or unsubstituted alkynyl group including 2 to 50 carbon atoms, a substituted or unsubstituted cycloalkyl group including 3 to 50 ring carbon atoms, a substituted or unsubstituted alkoxy group including 1 to 50 carbon atoms, a substituted or unsubstituted alkylthio group including 1 to 50 carbon atoms, a substituted or unsubstituted aryloxy group including 6 to 50 ring carbon atoms, a substituted or unsubstituted arylthio group including 6 to 50 ring carbon atoms, a substituted or unsubstituted aralkyl group including 7 to 50 carbon atoms, —Si (R121)(R122)(R123), —C(═O)R124, —COOR125, —N(R126)(R127), a halogen atom, a cyano group, a nitro group, a substituted or unsubstituted aryl group including 6 to 50 ring carbon atoms, a substituted or unsubstituted heterocyclic group including 5 to 50 ring atoms, or a group represented by -L101-Ar101;
one or more pair of two or more adjacent among R101 to R110 may form a saturated or unsaturated ring;
R121 to R127 are independently a hydrogen atom, a substituted or unsubstituted alkyl group including 1 to 50 carbon atoms, a substituted or unsubstituted aryl group including 6 to 50 ring carbon atoms, or a substituted or unsubstituted heterocyclic group including 5 to 50 ring atoms;
provided that at least one of R101 to R110 is a group represented by -L101-Ar101; L101 is a single bond, a substituted or unsubstituted arylene group including 6 to 30 ring carbon atoms, or a substituted or unsubstituted heteroarylene group including 5 to 30 ring atoms; Ar101 is a substituted or unsubstituted aryl group including 6 to 50 ring carbon atoms, or a substituted or unsubstituted heterocyclic group including 5 to 50 ring atoms; when two or more L101s are present, two or more L101s may be the same as or different from each other; when two or more Ar101s are present, two or more Ar101s may be the same as or different from each other; and when two or more R121s to R127s are present, each of two or more R121s to R127s may be the same as or different from each other.
