Embodiment 1

[0079] synthetic ligand

[0080] 1.00 parts of 9,9-diethyl-9-hydrogen-fluoren-2-ylboronic acid (9,9-diethyl-9H-fluoren-2-ylboronic acid), 0.42 parts of 4,4'-dibromo-2, 2'-bispyridine (4,4'-dibromo-2,2'-bipyridine) and 0.09 parts of tetrakis (triphenylphosphine) palladium (tetrakis(triphenylphosphine) palladium) were added to 50 parts of toluene and stirred to mix. 5.64 parts of 2M sodium carbonate aqueous solution were added by syringe, and the reaction mixture was heated to 100° C. for 12 hours. The product was extracted with dichloromethane, then washed with water and then dehydrated with magnesium sulfate, and the residue after solvent removal was eluted with silica gel column and chromatographed with dichloromethane / methanol After purification, the ligand of formula (II-1) of the present invention is obtained.

Embodiment 2

[0082] Synthesis of ruthenium metal complexes

[0083] 0.10 parts of [RuCl 2 (p-cymene)] 2 and 0.20 parts of (II-1) ligand were dissolved in 30 ml of dehydrated dimethyl formamide (dimethyl formamide), and the solution was heated to 80 ° C under nitrogen for 4 hours, and then added 0.08 parts 4,4'-dicarboxylic acid-2,2'-bipyridine (4,4'-dicarboxylic acid-2,2'-bipyridine, H 2 dcbpy), and heated to 160 ° C for 4 hours, the above chemical reaction must be carried out in the dark to avoid the isomerization reaction caused by light to produce isomers. Next, add 0.98 parts of ammonium thiocyanate (ammonium thiocyanate, NH 4NCS), and controlled the reaction temperature to react at 130°C for 5 hours. After the reaction was finished, evaporate the solvent with a rotary evaporator (rotary-evaporator), then add a large amount of water to dissolve excess ammonium thiocyanate, then filter and collect the water-insoluble product with a sintered glass filter (sintered glass filter), and ...

Embodiment 3

[0085] synthetic ligand

[0086] 1.42 parts of 9,9-dihexyl-9-hydrogen-fluoren-2-ylboronic acid (9,9-dihexyl-9H-fluoren-2-ylboronic acid), 0.42 parts of 4,4'-dibromo-2,2 '-Bipyridine and 0.09 parts of tetrakis(triphenylphosphine)palladium were added to 50 parts of toluene and stirred, and 5.64 parts of 2M aqueous sodium carbonate solution was added by syringe, and the reaction mixture was heated to 100°C for 12 hours. This product is extracted with dichloromethane, then washed with water and then dehydrated with magnesium sulfate, and the residue after the solvent is extracted is purified by silica gel column with dichloromethane / methanol eluting chromatography to obtain the product of formula (II-2) of the present invention. Ligand.

Abstract

The invention relates to a ruthenium metal complex compound with a structure indicated as the following formula (I), wherein L, L' and X are defined in the description. The ruthenium metal complex compound can be applied to a dye-sensitized solar cell (DSSC), and has excellent opto-electrical properties.

Description

technical field [0001] The invention relates to a ruthenium metal complex, in particular to a ruthenium metal complex suitable for a dye-sensitized solar cell (Dye-Sensitized Solar Cell, DSSC). Background technique [0002] With the development of human civilization, the world is facing serious energy crisis and environmental pollution. Using photoelectric solar cells to directly convert solar energy into electrical energy is one of the important methods to solve the world's energy crisis and reduce environmental pollution; among them, dye sensitization Solar cells have become a promising new type of solar cells due to their low manufacturing cost, large area, flexibility, and light transmission, which can be used in buildings. [0003] in recent years, et al published a series of literature on dye-sensitized solar cells (such as O'Regan, B.; , M. Nature 1991, 353, 737), showing the practicality of dye-sensitized solar cells. Generally speaking, the structure of dye-sen...
