摘要:

次氯酸根(ClO-)在人体免疫系统中发挥着重要的作用,其识别与检测备受关注。 本文设计合成了一种含有喹唑啉酮骨架的腙型荧光探针(HEMQ),并通过1H NMR、13C NMR、高分辨质谱(HRMS)表征了其结构。 探针HEMQ在V(乙醇):V(水)=1:1(c(PBS)=0.02 mol/L,pH=8.7)溶液中对ClO-具有良好的选择性且响应快速,荧光发生显著猝灭。 探针HEMQ对ClO-具有较高的灵敏度,检测限为1.0×10-4 mol/L。 此外,ClO-可引起探针溶液由黄色到无色的颜色变化,因此HEMQ可作为比色、荧光双通道响应的ClO-探针。

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.
