1. A compound represented by the general formula (1) below:

OG Complex Work Unit Chemistry
where R1, R2, R4, R7, R9, R10, R11, R12, R14, R17, R19 and R20 represent a hydrogen atom,
R5, R6, R15, R16 represent a hydrogen atom, and R3, R8, R13 and R18 represent an alkoxy group with 1 to 20 carbon atoms; or R5 and R6; and R15 and R16 are, in each combination, bonded to each other to form a ring via a single bond, and R3, R8, R13 and R18 represent a diphenylamino group substituted with an alkoxy group having 1 to 20 carbon atoms;
X1 and X2 each represent a divalent group represented by the general formula (2) below; and
Y represents CR21R22,
where R21 and R22 each independently represent an acyl group having 1 to 10 carbon atoms and optionally having a substituent, or an alkoxycarbonyl group having 1 to 10 carbon atoms and optionally having a substituent,

OG Complex Work Unit Chemistry
where R23 to R28 each independently represent a hydrogen atom, a linear or branched alkyl group having 1 to 10 carbon atoms and optionally having a substituent, a linear or branched alkenyl group having 2 to 10 carbon atoms and optionally having a substituent, a cycloalkyl group having 3 to 10 carbon atoms and optionally having a substituent, an aromatic hydrocarbon group having 6 to 18 carbon atoms and optionally having a substituent, or a heterocyclic group having 5 to 18 ring-forming atoms and optionally having a substituent;
R23 and R24; R25 and R26; and R27 and R28 are, in each combination, optionally bonded to each other to form a ring;
