These conjugated derivatives are linked through a double bond favoring electronic communication, and together with their planar geometry, can strongly aggregate under solvophobic environments, leading to aggregation and exhibiting significant AIE behavior. The double bond between electroactive units is prone to nucleophilic addition reactions by cyanide ions, selectively, conducive to turning off the fluorescence properties, making this hybrid system an efficient probe for cyanide ions. These studies were theoretically explained using DFT and TD-DFT calculations.<\/jats:p>","DOI":"10.3390\/ijms252312896","type":"journal-article","created":{"date-parts":[[2024,12,2]],"date-time":"2024-12-02T05:43:43Z","timestamp":1733118223000},"page":"12896","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Methoxyquinolone\u2013Benzothiazole Hybrids as New Aggregation-Induced Emission Luminogens and Efficient Fluorescent Chemosensors for Cyanide Ions"],"prefix":"10.3390","volume":"25","author":[{"given":"Mario","family":"Mutis-Ayala","sequence":"first","affiliation":[{"name":"Grupo de Investigaci\u00f3n en Compuestos Heteroc\u00edclicos, Universidad del Atl\u00e1ntico, Puerto Colombia 081007, Colombia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4516-213X","authenticated-orcid":false,"given":"Jorge","family":"Trilleras","sequence":"additional","affiliation":[{"name":"Grupo de Investigaci\u00f3n en Compuestos Heteroc\u00edclicos, Universidad del Atl\u00e1ntico, Puerto Colombia 081007, Colombia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3655-1838","authenticated-orcid":false,"given":"Richard","family":"D\u2019Vries","sequence":"additional","affiliation":[{"name":"Grupo de Investigaci\u00f3n en Qu\u00edmica de Productos Naturales, Departamento de Qu\u00edmica, Facultad de Ciencias Naturales, Exactas y de la Educaci\u00f3n, Universidad del Cauca, Calle 5 # 4\u201370, Popay\u00e1n 190003, Colombia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2749-8489","authenticated-orcid":false,"given":"Mario A.","family":"Mac\u00edas","sequence":"additional","affiliation":[{"name":"Cristalograf\u00eda y Qu\u00edmica de Materiales, CrisQuimMat, Facultad de Ciencias, Departamento de Qu\u00edmica, Universidad de los Andes, Cra. 1 #18a-12, Bogot\u00e1 111711, Colombia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alberto","family":"Insuasty","sequence":"additional","affiliation":[{"name":"Grupo de Investigaci\u00f3n de Compuestos Heteroc\u00edclicos, Departamento de Qu\u00edmica, Universidad del Valle, Calle 13 # 100\u201300, Cali 760032, Colombia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3256-0961","authenticated-orcid":false,"given":"Rodrigo","family":"Abonia","sequence":"additional","affiliation":[{"name":"Grupo de Investigaci\u00f3n de Compuestos Heteroc\u00edclicos, Departamento de Qu\u00edmica, Universidad del Valle, Calle 13 # 100\u201300, Cali 760032, Colombia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9451-3063","authenticated-orcid":false,"given":"Jairo","family":"Quiroga","sequence":"additional","affiliation":[{"name":"Grupo de Investigaci\u00f3n de Compuestos Heteroc\u00edclicos, Departamento de Qu\u00edmica, Universidad del Valle, Calle 13 # 100\u201300, Cali 760032, Colombia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2062-9589","authenticated-orcid":false,"given":"Luis A.","family":"Illicachi","sequence":"additional","affiliation":[{"name":"Grupo de Investigaci\u00f3n en Qu\u00edmica y Biotecnolog\u00eda, Facultad de Ciencias B\u00e1sicas, Universidad Santiago de Cali, Calle 5 # 62-00, Cali 760035, Colombia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7503-1528","authenticated-orcid":false,"given":"Edgar","family":"M\u00e1rquez","sequence":"additional","affiliation":[{"name":"Departamento de Qu\u00edmica y Biolog\u00eda, Divisi\u00f3n de Ciencias B\u00e1sicas, Universidad del Norte, Km 5 v\u00eda Puerto Colombia, Barranquilla 081007, Colombia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9662-9505","authenticated-orcid":false,"given":"Daniel","family":"Insuasty","sequence":"additional","affiliation":[{"name":"Departamento de Qu\u00edmica y Biolog\u00eda, Divisi\u00f3n de Ciencias B\u00e1sicas, Universidad del Norte, Km 5 v\u00eda Puerto Colombia, Barranquilla 081007, Colombia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,11,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"8657","DOI":"10.1039\/D3RA00749A","article-title":"Recent Advances in the Synthesis of Pharmaceutically Active 4-Quinolone and Its Analogues: A Review","volume":"13","author":"Dine","year":"2023","journal-title":"RSC Adv."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"120440","DOI":"10.1016\/j.envpol.2022.120440","article-title":"Fluoroquinolone Antibiotics: Occurrence, Mode of Action, Resistance, Environmental Detection, and Remediation\u2014A Comprehensive Review","volume":"315","author":"Bhatt","year":"2022","journal-title":"Environ.
