Patent ID: 8884029

Claim:
A dye for a photoelectric conversion device, comprising a cyanine compound represented by Chemical formula (3): wherein: ring A is a benzene ring, a naphthalene ring, a benzene ring having one or more substituent groups, or a naphthalene ring having one or more substituent groups; R5 to R10 and R12 to R14 are independently a hyrdrogen atom, a hydroxyl group, an alkyl group, an alkoxy group, an alkyl group having one or more substituent groups, an alkoxy group having one or more substituent groups, or a group represented by Chemical formula (2); at least one of R5 and R6 and at least one of R7 and R8 may be respectively detached to form an unsaturated bond, or may be respectively linked with each other to form a ring structure; Y1 and Y2 are each an anchor group represented by —R19-Z1, where R19 is an alkylene group, and Z1 is a carboxylic acid group or a carboxylic acid ion group; Q is a linkage group that has a methine chain having from 1 to 7 carbon atoms as a skeleton and that has one or more cyano groups, and if the methine chain has an odd number of carbon atoms, one of the one or more cyano groups is bonded to the center carbon atom of the methine chain; X2 is a group represented by —C(R12)(R13)- or —N(R14)-, a sulfur atom, an oxygen atom, a selenium atom, or a tellurium atom; An q− is an anion with q valency; q is 1 or 2, and p is a coefficient to maintain neutral electric charge; and Chemical formula (2) is: where: a bond between L1 and T1 is a double bond or 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; x and y being 0 where T1 is an oxygen atom, and (y+z) is 0 or 1 where T1 is a nitrogen atom; R15 to R17 are independently a hydrogen atom, a hydroxyl group, a nitro group, a cyano group, a halogen atom, an alkyl group having from 1 to 4 carbon atoms, or an alkyl group having from 1 to 4 carbon atoms substituted by one or more halogen atoms; R18 is a hydrogen atom, a hydroxyl group, a nitro group, a cyano group, a halogen atom, an alkyl group having from 1 to 4 carbon atoms, an alkoxy group having from 1 to 4 carbon atoms, an alkyl group having from 1 to 4 carbon atoms substituted by one or more halogen atoms, or an alkoxy group having from 1 to 4 carbon atoms substituted by one or more halogen atoms; R15 and R18/R16 and R17 may be respectively linked with each other to form a ring structure; and n is an integer from 0 to 4; wherein at least one of R9 and R10 of Chemical formula (3) is an alkyl group having from 6 to 25 carbon atoms.
