Compound <jats:bold>1Me<\/jats:bold> is virtually nonfluorescent in solution but emits a strong yellow fluorescence in the solid state because of the intramolecular C\u2212H\u22c5\u22c5\u22c5O H\u2010bond, which inhibits the free rotation of the exocyclic C\u2212C single bond of <jats:bold>1Me<\/jats:bold>. The nucleophilic addition of CN<jats:sup>\u2212<\/jats:sup> to the <jats:italic>\u03b2<\/jats:italic>\u2010conjugated carbon of the indanedione group of <jats:bold>1Me<\/jats:bold>, which breaks the intramolecular C\u2212H\u22c5\u22c5\u22c5O H\u2010bond and blocks ICT, causes the colorimetric and fluorometric responses of <jats:bold>1Me<\/jats:bold> to CN<jats:sup>\u2212<\/jats:sup>. Furthermore, inexpensive and portable paper\u2010based test kits containing <jats:bold>1Me<\/jats:bold> could be used to rapidly and conveniently sense CN<jats:sup>\u2212<\/jats:sup> using the naked eye in real time. The results provide a new strategy for designing colorimetric and fluorometric cyanide\u2010selective sensors based on an intramolecular C\u2212H\u22c5\u22c5\u22c5O hydrogen bonded solid emitter.<\/jats:p>","DOI":"10.1002\/asia.202200898","type":"journal-article","created":{"date-parts":[[2022,10,9]],"date-time":"2022-10-09T22:03:33Z","timestamp":1665353013000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Intramolecular C\u2212H\u22c5\u22c5\u22c5O Hydrogen\u2010Bonded Solid Emitter as Colorimetric and Fluorometric Cyanide\u2010Selective Chemodosimeter"],"prefix":"10.1002","volume":"17","author":[{"given":"Sachin D.","family":"Padghan","sequence":"first","affiliation":[{"name":"Department of Chemical Engineering Feng Chia University  40724 Taichung R.O.C.
