A compound represented by the following formula (1):
Claims35
A compound represented by the following formula (1):
- wherein in the formula (1),
- at least one of A1 and A2 is a monovalent residue of a compound represented by the following formula (a2):
- wherein in the formula (a2),
- X51 to X58 are independently CH, C(Rb) or N;
- Rb is a substituent, and when plural Rbs are present, the plural Rbs may be the same as or different from each other, and two selected from the plural Rbs may be bonded to each other to form a ring;
- Y is an oxygen atom, a sulfur atom, or —NRd and
- Rd, Re and Rf are independently a hydrogen atom or a substituent Rb, and when both Re and Rf are Rb, the Rbs may be bonded to each other to form a ring;
- A1 or A2 that is not the monovalent residue of a compound represented by the formula (a2) is a substituted or unsubstituted aryl group including 6 to 50 ring carbon atoms or a substituted or unsubstituted heteroaryl group including 5 to 50 ring atoms other than the monovalent residue of a compound represented by the formula (a2);
- L1 and L2 are independently a single bond, a substituted or unsubstituted arylene group including 6 to 60 ring carbon atoms or a substituted or unsubstituted heteroarylene group including 5 to 50 ring atoms;
- X1 to X8 are independently CH, C(Ra) or N;
- *1 to *4 are independently an atomic bonding that forms a single bond;
- any adjacent two of Y1 to Y4 are Cs that independently form a single bond with *1 and *2, and remaining two of Y1 to Y4 are independently CH, C(Ra) or N;
- any adjacent two of Y5 to Y8 are Cs that independently form a single bond with *3 and *4, and remaining two of Y5 to rare independently CH, C(Ra) or N;
- and
- Ra is a substituent, and if plural Ras are present, they may be the same as or different from each other, and two selected from the plural Ras may be bonded to each other to form a ring.
