Claim 8:
9. A compound represented by Formula (1A),, in Formula (1A), Dye1 represents a colorant structural part obtained by removing n1 hydrogen atoms from a compound represented by Formula (2A),, in Formula (2A), A represents a heterocyclic group and B represents an aryl group, a heterocyclic group, or —CH=G, in which G represents a heterocyclic group,
Q1 represents a structural part satisfying the following (i) and (ii),
(i) an energy level difference between a highest occupied molecular orbital and a lowest unoccupied molecular orbital is 2.9 eV or more,
(ii) an absolute value of the energy level of the lowest unoccupied molecular orbital is lower than an absolute value of an energy level of a lowest unoccupied molecular orbital of Dye, or an absolute value of the energy level of the highest occupied molecular orbital is lower than an absolute value of an energy level of a highest occupied molecular orbital of Dye,
L1 represents a divalent linking group in which a linking part with Q1 is composed of an alkylene group, or a divalent linking group which is directly bonded to a ring-constituting carbon atom of an aliphatic ring included in Q1, and
n1 represents an integer of 1 to 4,
wherein Dye1 is a structure up to a portion where a conjugated structure is interrupted due to that the structure of Formula (2A) is linked to L1, and
wherein Q1 represents a structural part obtained by removing one hydrogen atom from a compound represented by any one of Formulae (5) to (13),, R5 to R20, R22, R23, R25 to R27, R30 to R36, R37a to R37e, and R38 to R42 represent a hydrogen atom or a substituent,
R21 and R24 represent a hydrogen atom, an alkyl group, an aryl group, or a heterocyclic group, provided that, in a case where R21 and R24 are hydrogen atoms, Q1 is bonded to the linking group L1 at a nitrogen atom position from which the hydrogen atom has been removed,
X1 represents an oxygen atom, a sulfur atom, or a carbon atom, and
n represents an integer of 1 to 3.
