Abstract:
1. A dye for a photoelectric conversion device, wherein the dye has a cyanine structure represented by Formula (1): where: R1 and R2 are independently: a and b are independently an integer of 0 to 4; R3, R4, R5, and R6 are independently: at least one of R3 and R4 and at least one of R5 and R6 may be respectively detached to form a double bond, or may be respectively linked with each other to form one or more ring structures; X1 is a group represented by —C(R7)(R8)-, a group represented by —N(R9)-, a sulfur atom, an oxygen atom, a selenium atom, or a tellurium atom; X2 is a group represented by —C(R10)(R11)-, a group represented by —N(R12)-, a sulfur atom, an oxygen atom, a selenium atom, or a tellurium atom; R7, R8, R10, and R11 are independently: R9 and R12 are independently: Y1 and Y2 are independently: at least one of Y1 and Y2 is an anchor group; Q is a linkage group selected from the group consisting of linkage groups represented by Formulas (7-1) to (7-10): where R43 to R49 are independently a hydrogen atom, a hydroxyl group, a halogen atom, a cyano group, an aryl group having from 6 to 30 carbon atoms, a diphenyl amino group, an alkyl group having from 1 to 8 carbon atoms, or an alkoxyl group having from 1 to 8 carbon atoms; An p is 1 or 2; q is a coefficient to maintain neutral electric charge; Formula (2) has the following structure: where: the bond between L1 and T1 is a double bond or a triple bond; L1 represents a carbon atom; T1 represents a carbon atom, an oxygen atom, or a nitrogen atom; x, y, and z are independently 0 or 1, wherein x and y are 0 if T1 is an oxygen atom, and (y+z) is 0 or 1 if T1 is a nitrogen atom; R21, R22, and R23 are independently a hydrogen atom, a hydroxyl group, a nitro group, a cyano group, a halogen atom, an alkyl group having 1 to 4 carbon atoms, or a halogenated alkyl group having 1 to 4 carbon atoms; R24 is a hydrogen atom, a hydroxyl group, a nitro group, a cyano group, a halogen atom, an alkyl group having 1 to 4 carbon atoms, an alkoxy group having 1 to 4 carbon atoms, a halogenated alkyl group having 1 to 4 carbon atoms, or a halogenated alkoxy group having 1 to 4 carbon atoms; R21 and R24/R22 and R23 may be respectively linked with each other to form one or more ring structures; and n is an integer of 0 to 4.
