A Colorimetric and Ratiometric Fluorescent Chemosensor with Three Emission Changes: Fluoride Ion Sensing by a Triarylborane- Porphyrin Conjugate

A Colorimetric and Ratiometric Fluorescent Chemosensor with Three Emission Changes: Fluoride Ion Sensing by a Triarylborane- Porphyrin Conjugate

Perturbation in the energy‐transfer pathway and of the π conjugation between the chromophores in a triarylborane–porphyrin conjugate on coordination of a fluoride ion to the boron center is assumed to account for the observation of the three emission bands (at 356, 670, and 692 nm). The system also...

Zusammenfassung:Perturbation in the energy‐transfer pathway and of the π conjugation between the chromophores in a triarylborane–porphyrin conjugate on coordination of a fluoride ion to the boron center is assumed to account for the observation of the three emission bands (at 356, 670, and 692 nm). The system also displays a colorimetric (purple to green, see picture, and red to bluish emission) response to fluoride ions.
