ABSTRACT

A novel fluorescent sensor, 1-((2-hydroxynaphthalen-1-yl)methylene) semicarbazide, was synthesized and characterized by infrared spectra, elemental analysis, electrospray ionization mass spectra. The fluorescent sensing behaviors of the sensor toward different metals ions, anions, and amino acids were determined by UV–vis and fluorescence spectroscopy. The fluorescent sensor exhibited obvious changes in its electronic and fluorescent spectral behavior in the visible region of the spectrum in the presence of aluminum ion with the lower detection limit was 8.9 × 10−9 M.
