Fluorescent chemodosimeters for fluoride ionsviasilicon-fluorine chemistry: 20 years of progress

Abstract

Critical commentary on and a brief summary of representative F− fluorescent probes, imaging agents and nanosensors based on Si–F chemistry are provided, followed by pointing out the limitations of current systems and possible future directions.

A Colorimetric Chemosensor Based on a Nozoe Azulene That Detects Fluoride in Aqueous/Alcoholic Media

“…inducing cleavage of an Si-O or Si-C bond (For a review, see: Chen et al, 2019.

Synthesis and characterization of poly(tetraphenylimidazole)s and their application in the detection of fluoride ions

“…Synthesis of 2-(4,5-diphenyl-1-(4 0 -vinyl-[1,1 0 -biphenyl]-4-yl)-1Himidazol-2-yl)phenol (2) Under nitrogen, a biphasic solution of imidazole (1.00 g, 2.14 mmol), 4-styrene boronic acid (0.38 g, 2.57 mmol), sodium carbonate (0.68 g, 6.42 mmol) and [Pd(PPh 3 ) 4 ] (3 mol%) in tetrahydrofuran (THF) and water (20 : 8; 56 mL) was heated at reux for 12 hours. The organic layer was separated and the aqueous layer was extracted twice (20 mL) with ethyl acetate.…”

A Simple Water-Soluble ESIPT Fluorescent Probe for Fluoride Ion with Large Stokes Shift in Living Cells

“… 32 − 34 However, for probes based on the first two mechanisms, they suffered from unsatisfactory selectivity or irreversibility. 35 − 37 35 − 37 Although desilylation-based probes for fluoride ion could overcome the above disadvantages, most of them could only need a high level of organic solvents or monitor tetrabutylammonium fluoride in organic solvents. Additionally, most of these reported had long reaction time or required cationic surfactant, cetyltrimethylammonium bromide (CTAB), to increase the reaction rate, which greatly restricted their practical application.…”
