| Abstract | Hydrazine (NH), as an important chemical raw material widely used in many fields, caused serious harm to human, food and environment. Therefore, a smart fluorescent probe TPC-NH with intramolecular charge transfer (ICT) process was fabricated for colorimetric and fluorescent differentiating of NH in many samples. When TPC-NH met NH, blue emission at 451 nm was obviously observed attributed to the interruption of ICT process, resulting in the formation of the hydrazone structure. Additionally, smartphone-assisted colorimetric and fluorescent sensing platforms had been developed for real-time monitoring of NH. Importantly, TPC-NH with low toxicity revealed its ability to image NH in HeLa cells, onion and Arabidopsis thaliana. Interestingly, a hydrogel-coated cotton swab sensor was developed with TPC-NH as recognition unit, which showed obvious color and emission changes after NH fumigation with fast response speed. Flexible fluorescent TPC-NH-glove was constructed for wearable NH detection and used to monitor NH in food and environment samples. In brief, the TPC-NH probe not only showed great potential in NH detection for environmental and food safety, but also provided a new method for wearable tracking platforms in toxic substance detection. |
