Chromogenic signaling of water traces by 1,8-naphthalohydrazoneanion complex …

b s t r a c t A naphthalo-1, 8-bis[(2,4-dinitrophenyl)hydrazone] sensor (K) was synthesized and characterized using UVevis, 1H NMR and fluorescence spectroscopy. The sensor showed strong colorimetric and spectral response upon the molar addition of acetate or fluoride ion (AcO
or F
) in acetonitrile. The complexed state (KF or KAcO) of the system showed significant reversibility properties, b…
