A series of benzothiazole-based compounds were synthesized and characterized. Among them, probe Z showed significant dual-functional performance which was capable of sensing pH change and Cu2+. Probe Z displayed fluorescent turn-on under alkaline conditions due to deprotonation of the hydroxyl group along with the obviously color change from colorless to mint green. Interestingly, it further achieved in ratiometric detection of Cu2+ through absorbance or fluorescence signals in strong alkaline condition. The limit of detection was calculated correspondingly as 0.37 μM and 1.35 μM, respectively. Especially, the combination of the XNOR and INHIBIT logic gates could be used to confirm that one medium was in neutrality or alkalinity condition. Moreover, Z was successfully used in real water samples and test paper for fast identification of Cu2+, respectively.

The invention aims to provide a fluorescent probe based on benzothiazole fluorophore and application of the fluorescent probe in hypochlorous acid detection. The fluorescent probe disclosed by the invention is a fluorescent probe for visually detecting pypocholoride. The fluorescent probe is an HBT methyl derivative. The invention verifies the fluorescence stability in different solvents, and is applied to linear detection of hypochlorous acid/pypocholoride based on the fluorescence stability. The probe disclosed by the invention can be prepared into a test paper sensor for quickly, visually and semi-quantitatively detecting the concentration of hypochlorous acid/pypocholoride in a solution on site.

Substituted merocyanine dyes were obtained by Knoevenagel condensation between formylated arylbenzothiazole and quaternary 2-alkylbenzothiazoles. The condensations were performed in the presence of sodium methoxide and the products were obtained with exce
