OG Complex Work Unit Chemistry
wherein, in Formula (1),
Ar1 represents an aromatic hydrocarbon group optionally having a substituent, or an aromatic heterocyclic group optionally having a substituent,
at least one Ar1 is represented by the following Formula (10):

OG Complex Work Unit Chemistry
wherein,
Ar11 and Ar12 each independently represent a divalent aromatic hydrocarbon group optionally having a substituent, or an aromatic heterocyclic group optionally having a substituent;
Ar13 to Ar15 each independently represent a hydrogen atom or a substituent; and
* represents a binding position;
X represents —C(R7)(R8)—, —N(R9)—, or —C(R11)(R12)—C(R13)(R14)—;
R1 and R2 each independently represent an alkyl group optionally having a substituent;
R7 to R9 and R11 to R14 each independently represent hydrogen, an alkyl group optionally having a substituent, an aralkyl group optionally having a substituent, or an aromatic hydrocarbon group optionally having a substituent;
a and b each independently represent an integer of 0 to 4, with (a+b) being 1 or larger;
c represents an integer of 1 to 3;
d represents an integer of 0 to 4; and
