2,2':6',2"-terpyridine-4,4',4"-tricarboxylic acid CAS: 216018-58-5 is N-containing tridentate ligand. It became rising in the world due to its complex with Ru(II) applied in dye-sensitized solar cell reached very high conversion efficiency (10.4%), reported by Michael Graetzel group from Swiss Federal Institute of Technology (
J. Am. Chem. Soc. 2001, 123, 1613-1624).
This big event has been attracted many organic chemists focusing on synthesis of
2,2':6',2"-terpyridine-4,4',4"-tricarboxylic acid CAS: 216018-58-5. The French chemists, Jerome Husson
et. al.from Universite de Frenche-Comte reported a practical synthetic route to make the ligand in larger scale, published on
Natural Protocols 2014, 9(1), 21-26 (https://www.nature.com/articles/nprot.2013.162). 2-Furaldehyde CAS:98-01-1 reacts with two molecules of
methyl 2-acetylisonicotinate CAS:138715-82-9 in subsequent aldol condensation, 1,4-addition, cyclization in the presence of ammonia to form the pyridine ring. Finally, oxidation under
potassium permanganate to split the furan ring to get the carboxylic acid group.
UCHEM has been making this chemical with same protocols in kilograms and supplied this chemical in kilograms to Dyesol from 2011.03. to 2012.11.
