OG Complex Work Unit Chemistry
wherein in the formula (1),
R11 to R17 and R61 to R64 each independently represent a hydrogen atom, an unsubstituted alkyl group having 1 to 20 carbon atoms, one of R42 and R45 represents a single bond bonding ring *b to ring *a, and the other of R42 and R45 not being a single bond bonded to *a, R41, R43 and R44 each independently represents a hydrogen atom, an unsubstituted alkyl group having 1 to 20 carbon atoms, R55 represents a position bonding ring *d to ring *c through L1,
R51, R52, R53, and R54, each independently represent a hydrogen atom, an unsubstituted alkyl group having 1 to 20 carbon atoms, one of R21 to R22 represents a single bond bonded to *d, and the others of R21 to Res than the single bond bonded to *d each independently represent a hydrogen atom, a substituted or unsubstituted alkyl group having 1 to 20 carbon atoms, or a substituted or unsubstituted aryl group having 6 to 50 ring carbon atoms, one of R31 to R38 represents a single bond bonded to *b, and the others of R31 to R38 than the single bond bonded to *b each independently represent a hydrogen atom, a substituted or unsubstituted alkyl group having 1 to 20 carbon atoms, or a substituted or unsubstituted aryl group having 6 to 50 ring carbon atoms, and
L1 represents a single bond, or an unsubstituted para-phenylene group, provided that
in R11 to R17, R21 to R28, R31 to R38, R41 to R45, R51 to R55, and R61 to R64, substituents adjacent to each other are not bonded to each other and do not form a ring.
