Also disclosed is a fluorination method comprising providing, a salt comprising a cation and an aryloxylate, and SO.sub.2F.sub.2 to a reaction mixture; reacting the SO.sub.2F.sub.2 and the ammonium salt to provide a fluorinated aryl species. Further disclosed a fluorination method comprising providing a compound having the structure ArOH to a reaction mixture; where Ar is an aryl or heteroaryl; providing SO.sub.2F.sub.2 to the reaction mixture; providing a fluorinating reagent to the reaction mixture; reacting the SO.sub.2F.sub.2, the fluorinating reagent and the compound having the structure ArOH to provide a fluorinated aryl species having the structure ArF.

Fluorescent compounds that have aggregation-induced emission (AIE) characteristics. The compounds can be utilized as lipid droplet (LD)-specific bio-probes in cell imaging, with high photostability and brightness. For example, the compounds can be used for specific two-photon LDs staining in live cells and deep-tissues at ultralow concentrations. The compounds exhibit a large Stokes shift (>110 nm), high solid fluorescence quantum yields (up to 0.30), a good two-photon absorption cross-section (45-100 GM at 860 nm), high biocompatibility, and good photostability.
