Abstract:
A novel compound represented by general formula (1), a carrier system comprising a carrier having the novel compound fixed thereon, and a photoelectric conversion device having the carrier system. In formula (1), Z is a C1-C50 conjugated group; R1 is a C6-C20 aromatic hydrocarbon group, a C7-C20 aromatic hydrocarbon group substituted by an aliphatic hydrocarbon group, or a C1-C20 aliphatic hydrocarbon group, each of which is substituted by carboxyl, cyano, amino, amide, or nitro, the aliphatic hydrocarbon group being optionally interrupted by -O-, etc.; R2 is hydrogen or an optionally substituted C1-C20 hydrocarbon group; R30, R31, R32, R33, R40, R41, R42, R43, and R44 are each hydrogen or an optionally substituted hydrocarbon group, and adjacent two of them may be connected to each other to form a ring; R5 is hydrogen or cyano; and R11 is represented by formula (11-1) or (11-2), wherein n, ring A, and the like are as defined in the description.
Abstract:
Disclosed is a novel compound represented by formula (1) below. In the formula, A represents an optionally substituted aromatic hydrocarbon ring or aromatic heterocyclic group, B represents a group including a chain of one to four pieces of one or more groups selected from groups represented by specific formulae (B-1) to (B-13) (such as -C=C- or -N=N-, specifically see the description), R1 to R3 each represent an optionally substituted hydrocarbon or hydrocarbonoxy group, at least one of R1 to R3 represents an optionally substituted hydrocarbonoxy group, R4 and R5 each represent an optionally substituted hydrocarbon group, R4 and R5 may be linked together to form a ring, and R4 and R5 may be each independently linked with A to form a ring.
Abstract:
This carrier system carries at least one type of sensitizing dye described in (A) below and at least one type of sensitizing dye described in (B) below: (A) a sensitizing dye having a À-conjugated group and at least one anchor group, wherein the À-conjugated group and every one of the anchor group(s) are connected by a spacer having at least one alkylene and having an atomicity of 5 to 20; and (B) a sensitizing dye having a À-conjugated group and at least one anchor group, wherein the À-conjugated group and at least one anchor group are connected by a direct bond or by a spacer having at least one alkylene and having an atomicity of 1 to 4. In (A) and (B), the spacer is composed of carbon atoms, or carbon atoms and oxygen atom(s) etc., under predetermined conditions (see Description), and may have a branched chain or a ring structure.
