A new fluorescent compound L1
derived from 1-pyrenemethylamine hydrochloride (A
) has been synthesized by classical Schiff-base reaction between (A
) and 8-hydroxyquinoline-2-carbaldehyde (B
) followed by a chemical reduction with NaBH4
. The chemical structure was confirmed by elemental analysis, FAB-MS spectrometry and by IR, UV-vis and 1
H-NMR spectroscopy. The photophysical characterization was achieved by UV-vis and emission spectroscopy and lifetime measurements. Compound L1
was explored as pH fluorescent chemosensor in water-acetonitrile (95.5/0.5 v:v) solutions.
