Abstract:

Based on benzothiazole as fluorophore, ethyl cyanoacetate as recognition group, a new fluorescent probe 3-(2-hydroxy-benzothiazole)-2-cyano-ethyl acrylate(HBT-CN) with dual detection ability for hydrazine hydrate and bisulfite was designed and synthesized. In DMSO/PBS(1:4, volume ratio) buffered condition, the probe displayed good selectivity towards hydrazine and bisulfite with approximate 5.6 times(500 nm) and 7.5 times(458 nm) fluorescence enhancement at 500 and 458 nm, respectively. 1H NMR, 13C NMR and HRMS results showed that during the detection process, HBT-CN undergoed a reduction-condensation reaction with N2H4·H2O, which form a aldehyde hydrazone and emited pale yellow fluorescent signal at 500 nm. And HBT-CN under went a nucleophilic addition reaction with bisulfite and emited blue fluorescent signal at 458 nm. So, differential qualitative and quantitative detection of N2H4·H2O and HSO3- can be achieved.
