We describe herein the synthesis and characterization of novel phenothiazine-based push\u2013pull chromogenic chemosensors suitable for naked eye cyanide sensing. Indeed, specific detections were achieved for cyanide with a LOD of ca 9.12 to 4.59 \u00b5M and, interestingly, one of the new chemosensors has also revealed an unprecedented affinity for acetate with a LOD of ca 2.68 \u00b5M. Moreover, as proof of concept for practical applications, a paper test strip was prepared allowing its use for efficient qualitative naked eye cyanide sensing.<\/jats:p>","DOI":"10.3390\/bios12060407","type":"journal-article","created":{"date-parts":[[2022,6,13]],"date-time":"2022-06-13T22:00:38Z","timestamp":1655157638000},"page":"407","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":16,"title":["Naked-Eye Chromogenic Test Strip for Cyanide Sensing Based on Novel Phenothiazine Push\u2013Pull Derivatives"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7887-0493","authenticated-orcid":false,"given":"Pedro","family":"Mart\u00edn V\u00e1rguez","sequence":"first","affiliation":[{"name":"Aix Marseille Univ, CNRS, CINaM, 13005 Marseille, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4090-0479","authenticated-orcid":false,"given":"Jean-Manuel","family":"Raimundo","sequence":"additional","affiliation":[{"name":"Aix Marseille Univ, CNRS, CINaM, 13005 Marseille, France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,6,13]]},"reference":[{"key":"ref_1","unstructured":"Bianchi, A., Bowman-James, K., and Garcia-Espana, E.
