OG Complex Work Unit Chemistry
wherein, in the general formula [1], Z1 and Z2 are each independently selected from an alkyl group that may have a substituent, an aryl group that may have a substituent, and an aralkyl group that may have a substituent,
R11 to R17 are each independently selected from a hydrogen atom and a substituent; the substituent is any one of an alkyl group that may have a substituent, an alkoxy group that may have a substituent, an aryl group that may have a substituent, a heterocyclic group that may have a substituent, and a halogen atom; R16 and R17 may be linked together to form a ring,
R21 and R22 are each independently selected from a hydrogen atom and a substituent; the substituent is any one of an alkyl group that may have a substituent, an aryl group that may have a substituent, and an aralkyl group that may have a substituent, and
Y1 to Y3 are each independently selected from C—H, C—CH3, a N atom, and (N+-L)(X−) where L is any one of an alkyl group that may have a substituent, an aryl group that may have a substituent, and an aralkyl group that may have a substituent, and X− represents an anion.
