Abstract

A multifunctional Schiff base fluorescent sensor (receptor L) was prepared and its metal ions and anions sensing properties were investigated. Receptor L exhibited an excellent selective fluorescence response toward Fe²⁺ and F⁻. It also showed colorimetric response (from colorless to yellow) toward Fe³⁺ among a series of ions. Moreover, the detection limits of receptor L for Fe²⁺ and F⁻ were determined to be 0.3 ppm and 25.7 ppb, respectively. The two detection limit values were sufficiently low to detect nano-molar concentration of Fe²⁺ and F⁻.
