Dinuclear ruthenium complex dye, ruthenium-osmium complex dye, photoelectric conversion element using any one of the complex dyes, and photochemical cell

摘要

The present invention relates to a binuclear ruthenium complex dye represented by the following general formula (1-1):
wherein R 01 represents a linear or branched alkyl group having 2 to 18 carbon atoms; X represents a counter ion; and n represents a number of the counter ions needed to neutralize a charge of the complex; and in which proton(s) (H + ) of one or more carboxyl groups (-COOH) may dissociate.
