| titleOfInvention | A novel fluorescent probe for the sequential detection of hydrazine hydrate and bisulfite and its synthesis and application |
| abstract | The invention relates to a novel fluorescent probe for sequentially detecting hydrazine hydrate and hydrogen sulfite and its synthesis and application, belonging to the technical field of analytical chemistry. The chemical structure of the probe is shown in formula (I), which can sequentially detect hydrazine hydrate and bisulfite based on ESIPT and ICT mechanisms. Due to the inhibition of ESIPT and ICT, the probe has no fluorescence in aqueous solution; when the hydrazine hydrate solution is added, the functions of ESIPT and ICT are restored, and the fluorescence at 615 nm is significantly enhanced; while in the "probe + hydrazine hydrate" system When the bisulfite solution was added continuously, the ICT effect was inhibited, making the maximum emission wavelength blue-shifted to 508 nm. Sequential detection of these two substances is achieved through a distinct fluorescence change. The fluorescent probe of the present invention is not only easy to operate, good in selectivity, high in sensitivity and stable in optical performance, but also provides important ideas for the development of multifunctional fluorescent probes. Formula I. |
