Patent ID: 7977570

Claim:
A photoelectric conversion device, using oxide semiconductor fine particles sensitized with a methine dye represented by the following formula (1): wherein n represents an integer of 0 to 7; R 1 represents an optionally-substituted aromatic residue, an optionally-substituted aliphatic hydrocarbon residue, or an acyl group; X is a linking group which is combined with a nitrogen atom bonded to a benzene ring a to form a heteroring, and represents —CH 2 CH 2 — or —(CH 2 ) 3 —; Y represents a hydrogen atom, an optionally-substituted aromatic residue, an optionally-substituted aliphatic hydrocarbon residue, a carboxyl group, a phosphoric acid group, a sulfonic acid group, a cyano group, an amide group, or an alkoxycarbonyl group; Z represents an optionally-substituted aromatic residue, an optionally-substituted aliphatic hydrocarbon residue, or an acyl group; A 1 , A 2 and A 3 each independently represent an optionally-substituted aromatic residue, an optionally-substituted aliphatic hydrocarbon residue, a hydroxyl group, a phosphoric acid group, a cyano group, a hydrogen atom, a halogen atom, a carboxyl group, a carbonamide group, an alkoxycarbonyl group, an arylcarbonyl group, or an acyl group, provided that when n is 2 or more and plural A 2 s and A 3 s are present, each of A 2 s and A 3 s may be identical to or different from each other, and when n is a value other than 0, plurals selected from A 1 and/or A 2 (s) and/or A 3 (s) may form an optionally-substituted ring; the benzene ring a may have, as substituent(s) other than X and the nitrogen atom shown in the formula (1), 1 to 3 substituents selected from a group consisting of: halogen atoms; amide, hydroxyl, cyano, nitro, alkoxyl, acyl, and substituted or unsubstituted amino groups; and optionally-substituted aliphatic hydrocarbon residues and optionally-substituted aromatic residues, provided that when plural said substituents are plural, these substituents may be bonded with each other, thereby forming an optionally-substituted ring.
