Verwenden
2,2';6',2"-terpyridine is widely utilized in the field of supramolecular chemistry, which is used to manufacture the racks, ladders and grids, helicates, catenanes and dendrimers. It plays an important role as a ligand in coordination chemistry. Its complexes are employed in the oxidation of alcohols, the carbonylation of aromatic compounds and as oxygen-binding molecules. Functionalized terpyridine ligands were used in semiconductors and solar panels. It forms chealate complexes with europium(III) and terbium(III), which is used in protein labelling.
Definition
ChEBI: A tridentate heterocyclic ligand that binds metals at three meridional sites giving two adjacent 5-membered MN2C2 chelate rings.
Allgemeine Beschreibung
2,2′:6′,2′′;-Terpyridine is a tridentate ligand that can be prepared in two steps starting from 2-acetylpyridine.
Kontakt-Allergie
This molecule is a terpyridine with a 4-methyl substitution. A case of occupational dermatitis was reported in a chemical technician with no cross-reactivity to pyridine derivatives.
l?uterung methode
Crystallise it from diethyl ether, toluene or from pet ether, then aqueous MeOH, followed by sublimation in a vacuum at 90o. It is used for estimating Ag and Ru. [Kamra et al. Anal Chim Acta 81 177 1976, Beilstein 26 III/IV 258.]
