Abstract: A compound represented by the following formula (1):




One of R1 and R2 is a methyl group, and the other is an unsubstituted phenyl group, and R1 and R2 are not bonded to each other and therefore do not form a ring structure. One of R3 and R4 is a methyl group, and the other is an unsubstituted phenyl group, and R3 and R4 are not bonded to each other and therefore do not form a ring structure. R11 to R18, and R21 to R28 are hydrogen atoms, provided that, one selected from R11 to R18 is a single bond bonded to *a, and one selected from R21 to R28 is a single bond bonded to *b. L1 and L2 are each independently a single bond, or a substituted or unsubstituted phenylene group.
