An easy-to-prepare chemosensor, (E)-1-(phthalazine-4-yl)-2-(1-(pyridine-2- yl)ethylidene) hydrazine (3), structurally characterized by single X-ray crystallography, is developed for the selective and sensitive detection ...

A novel and easy-to-synthesize colorimetric and fluorescent chemosensor 1 was developed for the highly selective and sensitive recognition of Fe3+ and Cu2+. Receptor 1 showed a detectable color change from yellow to colorless ...
