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,
—Si(R901)(R902)(R903),
—O—(R904),
—S—(R905),
—N(R906)(R907),
a substituted or unsubstituted aryl group including 6 to 50 ring carbon atoms, or
a substituted or unsubstituted monovalent heterocyclic group including 5 to 50 ring atoms;
R901 to R907 are as defined in the formula (11);
m1 is an integer of 0 to 4;
m2 is an integer of 0 to 5;
m3 is an integer of 0 to 7;
when each of m1 to m3 is 2 or more, a plurality of R120's may be the same as or different from each other; and
when each of m1 to m3 is 2 or more, a plurality of adjacent R120's form a substituted or unsubstituted, saturated or unsaturated ring by bonding with each other, or do not form a substituted or unsubstituted, saturated or unsaturated ring.
In one embodiment, L101 and L102 in the formula (11) are independently a substituted or unsubstituted arylene group including 6 to 14 ring carbon atoms.
In one embodiment, when L101 and L102 in the formula (11) are divalent linking groups, the linking groups are independently selected from groups represented by each of the following formulas (b1) to (b17).
