A noticeable change in the color of the solution, along with a prominent fluorescence enhancement, was observed upon the addition of cyanide. The color change was observed upon the nucleophilic addition of the cyanide anion to the electron\u2010deficient cyanoacrylate group of <jats:bold>1<\/jats:bold>. The spectral changes induced by the reaction were analyzed by comparison with two model compounds, such as compound <jats:bold>2<\/jats:bold> with dimethyl substituents and compound <jats:bold>3<\/jats:bold> without a cyanoacrylate group. An intramolecular charge\u2010transfer (ICT) mechanism played a key role in the sensing properties, and the mechanism was supported by DFT\/TDDFT calculations.<\/jats:p>","DOI":"10.1002\/asia.201200578","type":"journal-article","created":{"date-parts":[[2012,9,24]],"date-time":"2012-09-24T09:15:12Z","timestamp":1348478112000},"page":"2864-2871","source":"Crossref","is-referenced-by-count":76,"title":["Reaction\u2010Based Colorimetric and Ratiometric Fluorescence Sensor for Detection of Cyanide in Aqueous Media"],"prefix":"10.1002","volume":"7","author":[{"given":"Yan\u2010Duo","family":"Lin","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yung\u2010Shu","family":"Pen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Weiting","family":"Su","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kang\u2010Ling","family":"Liau","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yun\u2010Sheng","family":"Wen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chin\u2010Hsin","family":"Tu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chia\u2010Hsing","family":"Sun","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tahsin J.","family":"Chow","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2012,9,24]]},"reference":[{"key":"e_1_2_9_1_2","unstructured":"\u00a0"},{"key":"e_1_2_9_2_2","doi-asserted-by":"publisher","DOI":"10.1002\/1521-3757(20010202)113:3<502::AID-ANGE502>3.0.CO;2-A"},{"key":"e_1_2_9_2_3","doi-asserted-by":"publisher","DOI":"10.1002\/1521-3773(20010202)40:3<486::AID-ANIE486>3.0.CO;2-P"},{"key":"e_1_2_9_3_2","doi-asserted-by":"publisher","DOI":"10.1021\/ar050195l"},{"key":"e_1_2_9_4_2","doi-asserted-by":"publisher","DOI":"10.1021\/ol051609d"},{"key":"e_1_2_9_5_2","doi-asserted-by":"publisher","DOI":"10.1021\/jo060774j"},{"key":"e_1_2_9_6_2","doi-asserted-by":"publisher","DOI":"10.1021\/cr068046j"},{"key":"e_1_2_9_7_2","unstructured":"\u00a0"},{"key":"e_1_2_9_8_2","unstructured":"K.\u2005W.
