Naked Eye Detection

In recent years, the wide application of fluoride materials has grown rapidly, therefore excessive discharge in the surrounding environment, especially in drinking water and organic effluent, has become a potential hazard to humans, and has even resulted in fluorosis disease. The development of a highly effective and convenient method to recognize fluoride anions in surrounding environments seems necessary and urgent. Among which, the development of a colorimetric and fluorescence fluoride chemosensor with obvious color changing allowing for naked-eye detection with high sensitivity and selectivity is more interesting and challenging. In this minireview, current novel colorimetric and fluorescence chemosensors for fluoride anions by hydrogen-bond interaction are introduced, including obvious color changing by naked-eye detection, high sensitivity and selectivity, non-pollution and fluoride extraction ability, aqueous detection, and other additional functions. Finally, the perspective of the fluoride chemosensor design concept and potential evolution trends are pointed out.

Naked Eye Detection

Two polymers, linear P1 and cross-linked P2, are employed in anion sensing. P1 exhibits fluorescence sensing of HPPi with a detection limit of about 1.63 ppm in aqueous DMSO. P2 exhibits selective naked-eye detection of PPi/HPPi via an indicator displacement assay (IDA).

Homo Lumo

New NiII monobenzoporphyrins and chlorins were synthesized. One compound was used as a chemodosimeter for naked-eye detection of cyanide in nonaqueous media giving a new π-extended porphyrin product with NIR absorptions and a 1.47 V HOMO–LUMO gap.
