N2 - 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.
