Hydrogen bonding or deprotonation: on fluoride ion fluorescence sensing with 1,1′-bi-2-naphthol derivatives

Imidazopyridine–fluoride interaction: solvent-switched AIE effects via S⋯O conformational locking

Imidazopyridine-based carboxamide exhibiting the aggregation-induced emission phenomenon works effectively in fluoride ion detection through H-bond interaction and subsequent deprotonation.

Equilibrium acidities of BINOL type chiral phenolic hydrogen bonding donors in DMSO

The pK_a values of fifteen BINOL type chiral phenolic catalysts were determined by the overlapping indicator method in DMSO via UV spectrophotometric titrations. The pK_a values are in the range of 9.30–16.43.

A simple and effective 1,2,3-triazole based “turn-on” fluorescence sensor for the detection of anions

1,2,3-Triazole based chemosensor is synthesized using “Click chemistry” approach. Addition of fluoride ion “turn-on” the fluorescence response of probe.

Dipicrylamine as a colorimetric sensor for anions: experimental and computational study

Dipicrylamine exhibited colorimetric sensing of F⁻, OAc⁻ and H₂PO₄⁻, detectable by bared-eye, out of a large number of anions. Interestingly, F⁻ binds with one of the phenyl carbon of dipicrylamine.
