Title A name given to the resource Colorimetric and theoretical investigation of coumarin based chemosensor for selective detection of fluoride Subject The topic of the resource Chemosensor; Colorimetric; Coumarin; Density functional theory; Hydrogen bonding; Selective detection Description An account of the resource Coumarin based Sensor 1 has been designed and synthesized to recognize fluoride ion visually with high selectivity and sensitivity over other anionic analytes through color change from very faint yellow to pink in acetonitrile. The probable binding phenomenon in solution phase has been explained by 1H NMR study of sensor 1 with different concentration of fluoride ions. The binding constant of the sensor 1 with fluoride has been determined as 3.9 104 M?1 and the lower detection limit 6.5 M of the sensor 1 towards fluoride, which has made the sensor 1 as a promising backbone for selective detection of fluoride. For the practical application, test strips based on sensor 1 were fabricated, which could act as a convenient and efficient naked eye F?test kits. The experimentally observed absorption maxima along with its binding nature with fluoride ions also have been supported through theoretical calculations using density functional theory (DFT) calculations. 2022 Creator An entity primarily responsible for making the resource Maity S.; Maity A.C.; kumar Das A.; Roymahapatra G.; Goswami S.; Mandal T.K.
