Claim 0:
1. A compound represented by formula (1):, wherein:
each of R1 to R6 is independently an alkyl group having 1 to 20 carbon atoms or an aryl group having 6 to 18 ring carbon atoms;
a is an integer of 0 or 1, b is an integer of 0 or 1, c is an integer of 0 or 1, d is an integer of 0 or 1, e is an integer of 0 or 1, and f is an integer of 0 or 1; each of (R1)0, (R2)0, (R3)0, (R4)0, (R5)0, and (R6)0 respectively means that R1, R2, R3, R4, R5, or R6 is not present; adjacent two groups selected from R1 to R3 are not bonded to each other, thereby failing to form a ring structure; and adjacent two groups selected from R4 to R6 are not bonded to each other, thereby failing to form a ring structure;
wherein Ar is represented by any of formulae (b-1) to (b-3), to (c-3), (d-1) to (d-3), (e-1) to (e-2), (f-1) to (f-4), and (i-1) to (i-2):, wherein:
* is a bond to L1 in formula (1);
each R is independently an alkyl group having 1 to 20 carbon atoms or an aryl group having 6 to 18 ring carbon atoms, wherein adjacent two Rs in each formula are not bonded to each other and do not form a ring structure;
when Ar is represented by any of formulae (b-1) to (b-3), (c-1) to (c-3), (d-1) to (d-3), and (0-1) to (e-2), each p is independently an integer of 0, each q is independently an integer of 0, each r is independently an integer of 0, and (R)0 means that R is not present;
when Ar is represented by formula (f-1), (f-2), (f-3) or (f-4), each s is an integer of 0 or 1, q is an integer of 0 or 1, r is an integer of 0 or 1, and (R)0 means that R is not present;
when Ar is represented by formula (i-1), or (i-2), each q is independently an integer of 0 or 12 each r is independently an integer of 0 or 1 and (R)0 means that R is not present;
each of L1 to L3 is independently a single bond or an arylene group represented by formula (ii) or (iii):, wherein:
at least one of L2 and L3 is a single bond;
R is the same as defined with respect to formulae (b-1) to (b-3), (c-1) to (c-3), (d-1) to (d-3), e-1) to (e-2), (f-1) to (f-4), and(i-1) to (i-2);
q is independently an integer of 0;
when L1 is represented by formula (ii) or (iii), one of * and ** is a bond to Ar in formula (1), and the other is a bond to the nitrogen atom in formula (1);
when L2 is represented by formula or (iii), one of * and ** is a bond to the phenanthrene structure in formula (1), and the other is a bond to the nitrogen atom in formula (1); and
when L3 is represented by formula (ii) or (iii), one of * and ** is a bond to the phenanthrene structure in formula (1), and the other is a bond to the nitrogen atom in formula (1).
