Usage

Description

Z-907 dye, (cis-Ru(H2dcbpy)(dnbpy)(NCS)2, where the ligand H2dcbpy?is 4,4′-dicarboxylic acid-2, 2′-bipyridine and dnbpy is 4,4′-dinonyl-2,2′-bipyridine, is amphiphilic nature while the introduction of the two hydrophobic alkyl chains on the bipyridyl ligand is critical to provide an insulating barrier to avoid charge carrier recombination and also help enhance?thermal stability.

Uses

High-performance ruthenium-based dye used in dye-sensitized solar cells (DSCs) for the sensitization of Titania. Hydrophobic character due to the presence of C9 alkyl chains.

METHOD FOR SYNTHESIZING HETEROLEPTIC RUTHENIUM COMPLEX COMPOUNDS

Provided is a method for synthesizing heteroleptic ruthenium complex compound dyes, the method including the steps of (a) putting, in a first reactor, one or more solvents selected from a group consisting of a ruthenium(III) chloride hydrate, N-methylpyrrolidone, dimethylformamide and dimethylacetylamide, and a compound represented by chemical formula 1 below to be reacted; (b) putting, in a second reactor, one or more solvents selected from a group consisting of 2,2′-bipyridine-4,4′-dicarboxylic acid, N-methylpyrrolidone, dimethylformamide and dimethylacetylamide to be maintained at 120-150°C; (c) adding reaction solution of the first reactor in the second reactor to be maintained and reacted at 120-150°C; and (d) adding thiocyanic acid ammonium salts or a third ligand in the reaction solution of step (c) to be reacted and cooling the reactor. [Chemical formula 1] R and R′ are respectively independently hydrogen or an alkyl group of C1 to C20.
