OG Complex Work Unit Chemistry
where A represents a group having the structural formula (B-3) below, B, and C may be the same or different, and each represents a substituted or unsubstituted phenyl group, or a substituted or unsubstituted fused polycyclic aromatic group:

OG Complex Work Unit Chemistry
where the dashed line portion represents a binding site;
R represents a hydrogen atom, a heavy hydrogen atom, a fluorine atom, a chlorine atom, a cyano group, a nitro group, a linear or branched alkyl group having 1 to 6 carbon atoms and optionally having a substituent, a cycloalkyl group having 5 to 10 carbon atoms and optionally having a substituent, a linear or branched alkenyl group having 2 to 6 carbon atoms and optionally having a substituent, a linear or branched alkyloxy group having 1 to 6 carbon atoms and optionally having a substituent, a cycloalkyloxy group having 5 to 10 carbon atoms and optionally having a substituent, a substituted or unsubstituted aromatic heterocyclic group, a substituted or unsubstituted aromatic hydrocarbon group, a substituted or unsubstituted fused polycyclic aromatic group, or a substituted or unsubstituted aryloxy group; n is the number of Rs and represents an integer of 0; and
Ar1 and Ar2 may be the same or different, and each represent a substituted or unsubstituted aromatic hydrocarbon group, a substituted or unsubstituted aromatic heterocyclic group, or a substituted or unsubstituted fused polycyclic aromatic group, with the proviso that Ar1 and Ar2 are not a dibenzofuranyl group or a dibenzothienyl group.
