Abstract:

Hypochlorite(ClO-) displays essential roles in human immune system, the detection of which has aroused extensive attention. Herein, a hydrazone type fluorescent probe(HEMQ) that containing quinazolinone skeleton was designed and synthesized, and the structure of HEMQ was characterized by 1H NMR, 13C NMR, and HRMS analysis. In V(ethanol):V(water)=1:1(c(PBS)=0.02 mol/L, pH=8.7) solution, probe HEMQ exhibits rapid response and good selectivity toward ClO- through distinct fluorescence quenching. HEMQ displays good sensitivity to ClO- with a detection limit of 1.0×10-4 mol/L. In addition, ClO- can induce a color change from yellow to colorless of the probe solution, thus, probe HEMQ can act as a colorimetric and florescent dual-channel ClO- probe.
