A selective chromofluorogenic chemodosimeter for fluoride ions based on distyrylbenzenes derivatives containing dual Si-O groups.
A new chemodosimeter for fluoride ions based on F(-) triggered dual Si-O bond cleavage of distyrylbenzenes derivatives was developed for the first time. Upon the addition of F(-) ions, the chemodosimeter (7) displayed apparent color changes from colorless to faint yellow, with a dramatic red-shift in the emission wavelength (~100 nm), and higher selectivity for fluoride over other common anions. With the aid of fluorescence measurements, the limit of detection could be as low as 89.8 nm. Using a 'dipstick' approach, chemodosimeter (7) might serve as a prototype device for fluorescent detecting F(-) without the need for any additional equipment.
