title: A carbohydrate modified fluoride ion sensor and its applications.
abstract: A new fluorescent probe for the detection of F(-) (TBA(+) and Na(+) salts) has been developed, which is based on a desilylation triggered chromogenic reaction in water. This probe exhibits excellent F(-) ion selectivity as well as significant color changes visible to the naked eye at the concentration of 1.5 mg L(-1), the WHO recommended level of F(-) ions in drinking water. This new carbohydrate modified probe can be used directly in aqueous medium without using organic co-solvents. Furthermore, the probe presents high sensitivity and selectivity for the imaging of F(-) ions in HepG2 cells.
