Fluorescent molecules based on a fluorinated isoxazole scaffold were provided for the synthetic methods and their photochemical properties.  Simple 3,5-diarylisoxazoles led to increasing the fluorescent intensity and exhibited a redshift in the emission intensity by introducing a fluorine atom.  α-Fluorinated boron ketoiminates (F-BKIs) derived from a ring opening reaction of 4-fluoroisoxazoles were also synthesized and exhibited a highly fluorescent luminescence as a new aggregation-induced emission (AIE) fluorophore.
