Big Discount 4,4'-Dicarboxy-2,2'-bipyridine CAS 6813-38-3 With Best Quality
2,2'-Bipyridine-4,4'-dicarboxylic acid CAS:6813-38-3 is made from 4,4’-dimethyl-2,2’-bipyridine CAS: 1134-35-6 by oxidation, which shows off-white powder and is very hardly dissolved in most organic solvent. But its derivatives, dimethyl 2,2'-bipyridine-4,4'-dicarboxylate CAS: 71071-46-0;4,4'-Bis(hydroxymethyl)-2,2'-bipyridine CAS: 109073-77-0, etc. is shown very good solubility in many organic solvent.
2,2'-Bipyridine-4,4'-dicarboxylic acid CAS:6813-38-3 is key components of N719 dye. This bidentate ligand complexes with Ruthenium show long lifetime of its excited state, and also the oxidized Ru(III) center has a long-term chemical stability so that this Ru(III)-complex is suitable photosensitizer for Dye Sensitized Solar Cell(DSSC). Graetzel research group at the Swiss Federal Institute of Technology made N719 dye (2,2‘-Bipyridine-4,4’- -dicarboxylic acid complexes with Ru(II), NCS-1 as counter ion), applied in DSSC and achieved the solar energy conversion efficiency (η) of 7-10% under AM 1.5 irradiation.
2,2'-Bipyridine-4,4'-dicarboxylic acid CAS:6813-38-3 could be supplied in different size with competitive price.
