Synthesis and spectral properties of a novel fluorescent probe for Zn2++ based on a benzoxazole fluorophore.

A novel turn-on fluorescent probe containing a benzoxazole fluorophore has been synthesised and its response to different metal ions has been investigated by spectrometry. The probe was highly selective and sensitive to Zn2+and showed a complexation ratio towards Zn2+of 1:1. It also exhibited a linear response range for Zn2+from 0.3 to 4.8 μmol L–1 with a detection limit of 0.36 μmol L–1. [ABSTRACT FROM AUTHOR]
