Description

Description générale

1H-1,2,3-Triazolo[4,5-b]pyridine belongs to the class of triazolopyridine. It reacts with europium under solvothermal conditions in pyridine to yield the homoleptic framework containing Eu^II centers that are icosahedrally coordinated by the 12 nitrogen atoms of six chelating ligands. The surface-enhanced Raman (SER) spectra of 1H-1,2,3-triazolo[4,5-b]pyridine adsorbed on silver hydrosols is studied in the region 3500-100cm^-1.

Application

1H-1,2,3-Triazolo[4,5-b]pyridine (1,2,3-Triazolo(5,4-b)pyridine) may be used:
