By the nucleophilic attacking of CN\u2212 to the fluoroacetylamino group in the sensor, the additional reaction of CN\u2212 and carbonyl group induced the ICT (intramolecular charge transfer) effect in the molecule and caused the fluorescence quenching sensor. The titration experiments show that the sensor has good sensitivity, selectivity and quick response for CN\u2212. In addition, the fluorescent detection of CN\u2212 in the living cell and zebrafish experiments demonstrated the value of the sensor in tracing the CN\u2212 in biological systems.<\/jats:p>","DOI":"10.3390\/bios14010051","type":"journal-article","created":{"date-parts":[[2024,1,18]],"date-time":"2024-01-18T11:28:46Z","timestamp":1705577326000},"page":"51","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":20,"title":["A New Phenothiazine-Based Fluorescent Sensor for Detection of Cyanide"],"prefix":"10.3390","volume":"14","author":[{"given":"Yulei","family":"Li","sequence":"first","affiliation":[{"name":"School of Chemistry & Environmental Engineering, Jilin Provincial International Joint Research Center of Photo-Functional Materials and Chemistry, Changchun University of Science and Technology, Changchun 130022, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chen","family":"Zhou","sequence":"additional","affiliation":[{"name":"School of Chemistry & Environmental Engineering, Jilin Provincial International Joint Research Center of Photo-Functional Materials and Chemistry, Changchun University of Science and Technology, Changchun 130022, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiaxin","family":"Li","sequence":"additional","affiliation":[{"name":"School of Chemistry & Environmental Engineering, Jilin Provincial International Joint Research Center of Photo-Functional Materials and Chemistry, Changchun University of Science and Technology, Changchun 130022, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jing","family":"Sun","sequence":"additional","affiliation":[{"name":"School of Chemistry & Environmental Engineering, Jilin Provincial International Joint Research Center of Photo-Functional Materials and Chemistry, Changchun University of Science and Technology, Changchun 130022, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,1,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"132153","DOI":"10.1016\/j.foodchem.2022.132153","article-title":"Quantitatively analysis and detection of CN\u2212 in three food samples by a novel nopinone-based fluorescent probe","volume":"379","author":"Li","year":"2022","journal-title":"Food Chem."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"120644","DOI":"10.1016\/j.saa.2021.120644","article-title":"Benzoindoxazine derivatives containing carbazole for detection of CN\u2212 and its application in plant seed extracts and cell imaging","volume":"268","author":"Pan","year":"2022","journal-title":"Spectrochim.
