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

• 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,
• 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;
• Z represents an oxygen atom, a sulfur atom, or a selenium atom;
• and
• m and n represent integers of 0 to 2, with the proviso that cases where both m and n are 0 are excluded.
