摘要

合成了一种基于硝基苯并恶二唑(NBD)的比色化学传感器CNA (N,N,N‐三甲基‐2‐(2‐(7‐硝基苯并[c][1,2,5]恶二唑‐4‐基)肼基)‐2‐氧氧桑‐1‐氯化铵)。传感器CNA通过黄色到无色的颜色变化检测到ClO−。CNA对ClO−的检出限为0.36 μM。此外，还成功地将裸眼试纸条应用于ClO -检测。通过ESI - MS、FT - IR、1H NMR滴定和DFT计算证实了CNA对ClO -的探测机制是ClO -对CNA的水解裂解反应。这篇文章受版权保护。版权所有。

A nitrobenzodioxazole-based water-soluble chemosensor for colorimetric quantification of aqueous hypochlorite

A nitrobenzoxadiazole (NBD)-based colorimetric chemosensor CNA (N,N,N-trimethyl-2-(2-(7-nitrobenzo[c][1,2,5]oxadiazol-4-yl)hydrazineyl)-2-oxoethan-1-aminium chloride) was synthesised. The sensor CNA can detect hypochlorite (ClO⁻) via colour variation of yellow to colourless. The detection limit for ClO⁻ by CNA was analysed to be 0.36 μM. Moreover, the naked-eye test strip was successfully applied for ClO⁻ detection. The probing mechanism of CNA to ClO⁻ was proposed to be a hydrolytic cleavage reaction of CNA by ClO⁻ and was demonstrated by electrospray ionisation mass spectrometry (ESI-MS), Fourier-transform infrared (FTIR), proton nuclear magnetic resonance (¹H NMR) analysis and density functional theory (DFT) calculations.
