A functional applied material on recognition of metal ion zinc based on the double azine compound

A colorimetric and fluorescent probe L has been designed and synthesized, which bearing the double azine moiety and showing a detection limit of 2.725 × 10(−7) M towards Zn(2+). Based on the basic recognition mechanism of ESIPT and CHEF effect, the L has high selectivity and sensitivity to only Zn(2...

description A colorimetric and fluorescent probe L has been designed and synthesized, which bearing the double azine moiety and showing a detection limit of 2.725 × 10(−7) M towards Zn(2+). Based on the basic recognition mechanism of ESIPT and CHEF effect, the L has high selectivity and sensitivity to only Zn(2+) (not Fe(3+), Hg(2+), Ag(+), Ca(2+), Co(2+), Ni(2+), Cd(2+), Pb(2+), Cr(3+), and Mg(2+)) within the physiological pH range (pH = 7.0–8.4) and showed a fluorescence switch. Moreover, this detection progress occured in the DMSO/H(2)O ∼ HEPES buffer (80/20, v/v; pH 7.23) solution which can conveniently used on test strip.
