‘Naked-eye’ detection of F− ions by two novel colorimetric receptors

Reversible “OFF–ON” fluorescent and colorimetric sensor based benzothiazole-bisphenol A for fluoride in MeCN

“…6). The to through-space effects which polarize C-H bond in the proximity to hydrogen bond, create 1 partial positive charge on the proton, and cause a downfield shift [20,34]. These data support 2 that strong hydrogen bonding interactions between phenolic-OH protons and F -.…”

Pyrene Based Chemosensor for Selective Sensing of Fluoride in Aprotic and Protic Environment

“…The association constants for L with fluoride anion in DMSO medium were calculated from UV-Vis (K ass ) and fluorescence (K ass # ) studies by the linear BenesiHildebrand expression [15],…”

A family of highly selective fluorescent sensors for fluoride based on excited state proton transfer mechanism

“…Fluorescence quantum yields of fluoride-receptor complexes were measured against quinine sulphate as standard [10]. The association constants were calculated from UV-vis (K ass ) and fluorescence (K ass # ) studies by the linear Benesi-Hildebrand expression [11] (Table 1):…”
