Herein, an ultrasensitive and cost-effective coumarin based fluorescent strategy with a "turn-off" signal was developed for specific detection of trace Cu2+ ions. Synthesis of 6,7-dihydroxy-3-(3-methylphenyl)coumarin (TMAC) probe was performed and characterized. The developed fluorescent probe presented excellent selectivity. The limit of detection of the sensor can reach as low as 5.13 nM in ACN/H2O (v/v=95/5) buffered by 5 mu M HEPES buffer at pH = 7.0, and it is below the World Health Organization (WHO) guideline for drinking water (31.5 mu M). The probable stoichiometry of TMAC-Cu2+ complex (1:1) was determined by Job's plot method and confirmed by FT-IR and ESI-MS. We further successfully applied TMAC for Cu2+ detection in water and various beverage samples with good recovery (90.24-109.75 %).</dc:description> <dc:identifier>https://aperta.ulakbim.gov.trrecord/72097</dc:identifier> <dc:identifier>oai:zenodo.org:72097</dc:identifier> <dc:rights>info:eu-repo/semantics/openAccess</dc:rights> <dc:rights>http://www.opendefinition.org/licenses/cc-by</dc:rights> <dc:source>SUPRAMOLECULAR CHEMISTRY 31(12) 756-766</dc:source> <dc:title>An ultrasensitive and selective 'turn off' fluorescent sensor with simple operation for the determination of trace copper (II) ions in water and various beverage samples</dc:title> <dc:type>info:eu-repo/semantics/article</dc:type> <dc:type>publication-article</dc:type> </oai_dc:dc>
