Development of carbazole-based fluorescent probe for highly sensitive application in fluoride ion detection

Research Progress on Naphthalimide Fluorescent Probes

“…[51] However, studies have shown that if abnormal amounts of F − are absorbed into human body, this could result in a series of health problems. [52] Hence, considerable attention has been paid to develop sensors for fluoride ion detection in real-time.…”

A sensitive paper-based sensor for fluoride detection in water using Tb3+ photoluminescence

“…26 Thus, the strategy of desilylation of silyl ether has been widely used in synthesizing many chemodosimeters for fluoride sensing. 16,27 However, fluoride detection in aqueous solutions using these techniques is difficult due to the interference with other biomolecules and similar ions present in the samples. 28 Lanthanide photoluminescence can circumvent these problems by allowing emission recording in the time-gated mode due to long excited-state lifetimes with large pseudo-Stokes shifted sharp, line-like emission features.…”

Highly selective, sensitive, and visible detection of fluoride ions through transforming their roles from reactants to catalysts in the silicon corrosion reaction

“…Visual colorimetry usually uses organic complexes as indicators. 26,27 Fluoride ions with large electronegativity can easily complex with Lewis-acidic center ions in organic complexes, such as metal cations or silicon atoms, leading to changes in the complex structures. [28][29][30][31] These changes could, in turn, cause variations in the fluorescence or absorption spectrum of the organic complexes.…”
