Abstract

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.

一种用于次氯酸水溶液比色定量的硝基苯并二恶唑水溶性化学传感器

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。
