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 1.5mgL⁻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.
