The ring-chain isomerization of [1,2,3]triazolo[1,5-a]pyridines or [1,2,3]triazolo[1,5-a] quinolines was efficiently employed as a tool to provide tridentate fluorescent structures. Based on these scaffolds, a new family of highly fluorescent compds. was synthesized and evaluated for the recognition of zinc or copper cations. In addn., the 1:1 Zn+2-L complex of a naphthalene triazolopyridine-pyridine deriv. revealed high efficiency as sensor for anions providing large binding consts. for nitrite and cyanide.
