Abstract

The invention provides a method for producing a ruthenium complex, which can synthesize Ru(dcbpy)2(NCS)2 in a short time. The production method has the following steps: 1) reacting RuCl3.3H2O with dcbpy and synthesizing an intermediate Ru(II)(dcbpy)2Cl2; and 2) adding NH4NCS to synthesize the Ru(dcbpy)2(NCS)2, wherein separation and purification are needed to be carried out on the synthesized Ru(II)(dcbpy)2Cl2, and the step 1) and step 2) are performed in the same reactor, i.e. a one-pot method is used. Reacting conditions for each reaction in step 1) and step 2) are optimized, thus shortening the synthesis time, reducing generation of isomers, and obtaining the Ru(dcbpy)2(NCS)2 with high purity, high yield and low cost.

Description

technical field [0001] The present invention relates to the manufacture method that can be applicable to the ruthenium complex compound of dye-sensitized solar cell, relate in particular to short-time, high-purity, high-yield synthesis cis-bis(isothiocyanato)-bis(2,2 '-bipyridyl-4,4'-dicarboxylic acid) ruthenium (II) complex method. Background technique [0002] A solar cell utilizing sunlight has attracted attention as an energy source to replace fossil fuels, and various researches have been conducted on it. A solar cell is a photoelectric conversion device that converts light energy into electrical energy. Since it uses sunlight as an energy source, it has minimal impact on the global environment and is expected to be widely used. [0003] Dye-sensitized solar cells (hereinafter abbreviated as DSSC (Dye-Sensitized Solar Cell)) using light-induced electron movement sensitized by dyes have been receiving attention in recent years as next-generation solar cells replacing si...
