A compound represented by the following formula (1):
- wherein in the formula (1), C1 and C2 are independently a carbon atom;
- X1 to X4 are independently N, CH or C(R1);
- R1 are independently a single bond, a substituted or unsubstituted alkyl group including 1 to 20 carbon atoms, a substituted or unsubstituted cycloalkyl group including 3 to 18 ring carbon atoms, a substituted or unsubstituted alkoxy group including 1 to 20 carbon atoms, a substituted or unsubstituted cycloalkoxy group including 3 to 18 ring carbon atoms, a substituted or unsubstituted aryl group including 6 to 18 ring carbon atoms, a substituted or unsubstituted aryloxy group including 6 to 18 ring carbon atoms, a substituted or unsubstituted arylthio group including 6 to 18 ring carbon atoms, a substituted or unsubstituted heteroaryl group including 5 to 18 ring atoms, a substituted or unsubstituted heteroaryloxy group including 5 to 18 ring atoms, a substituted or unsubstituted amino group, a substituted or unsubstituted silyl group, a substituted or unsubstituted diaryloxyphosphonyl group, a fluoro group or a cyano group;
- provided that if two adjacent groups of X1 to X4 are both C(R1) and one of R1s a single bond, the single bond is used in the bond to the other R1 to form a ring comprising the two carbon atoms;
- L is independently a group represented by the following formula (2):
- -L1-(A)n (2)
- wherein in the formula (2), n is the number of A being bonded sequentially, and is an integer of 0 to 6;
- when n is 2 or more, plural As may be the same or different;
- A is a group selected from a substituted or unsubstituted alkyl group including 1 to 20 carbon atoms, a substituted or unsubstituted cycloalkyl group including 3 to 18 ring carbon atoms, a substituted or unsubstituted alkoxy group including 1 to 20 carbon atoms, a substituted or unsubstituted cycloalkoxy group including 3 to 18 ring carbon atoms, a substituted or unsubstituted aryl group including 6 to 18 ring carbon atoms, a substituted or unsubstituted aryloxy group including 6 to 18 ring carbon atoms, a substituted or unsubstituted arylthio group including 6 to 18 ring carbon atoms, a substituted or unsubstituted heteroaryl group including 5 to 18 ring atoms, a substituted or unsubstituted heteroaryloxy group including 5 to 18 ring atoms, a substituted or unsubstituted amino group, a substituted or unsubstituted silyl group, a substituted or unsubstituted diaryloxyphosphinyl group, a divalent group corresponding thereto, a fluoro group and a cyano group;
- L1 is a group represented by the following formula (3):
- wherein in the formula (3), C3 is a carbon atom, and C3 is bonded to C1 or C2 in the formula (1);
- Y1 is O, S, NH, N(R2) or a nitrogen atom that is bonded to A;
- X5 to X11 are independently N, CH, C(R3) or a carbon atom that is bonded to A;
- R2 and R3 are independently a single bond, a substituted or unsubstituted alkyl group including 1 to 20 carbon atoms, a substituted or unsubstituted cycloalkyl group including 3 to 18 ring carbon atoms, a substituted or unsubstituted alkoxy group including 1 to 20 carbon atoms, a substituted or unsubstituted cycloalkoxy group including 3 to 18 ring carbon atoms, a substituted or unsubstituted aryl group including 6 to 18 ring carbon atoms, a substituted or unsubstituted aryloxy group including 6 to 18 ring carbon atoms, a substituted or unsubstituted arylthio group including 6 to 18 ring carbon atoms, a substituted or unsubstituted heteroaryl group including 5 to 18 ring atoms, a substituted or unsubstituted heteroaryloxy group including 5 to 18 ring atoms, a substituted or unsubstituted amino group, a substituted or unsubstituted silyl group, a substituted or unsubstituted diaryloxyphosphinyl group, a fluoro group or a cyano group, provided that if two adjacent groups of X6 to X11 are both C(R3) and one of R3s is a single bond, the single bond is used in the bond to the other R3 to form a ring comprising the two carbon atoms.
