Terpyridines

Terpyridine is a polypyridine compound in which three pyridine molecules are bound with a single bond. Among many regiomeric terpyridines, 2,2’; 6,2”-terpyridines have special characteristic of forming stable complexes with transition metals. Many 2,2’; 6,2”-terpyridine derivatives have been used as tridentate ligands in combination with bipyridine derivatives for dye sensitized solar cell. Terpyridines have also been utilized for catalytic process and in asymmetric catalysis. Considering the versatility of terpyridines, Sapala has developed processes for multigram scale synthesis of terpyridines. Sapala also continues its efforts to make new derivatives of terpyridines, including unsymmetrical derivatives of terpyridines and terpyridine derivatives with extended conjugation at 4,4’,4”-positions.

The following are the representative examples of terpyridines.
