A new fluorescent chemosensor based on bithiophene coupled dimesitylborane (BMB-1)(I) was synthesized and characterized. BMB-1 was used for colorimetric and turn-on fluorescent sensing of cyanide (CN-) and fluoride (F-) ions, in the presence of other competitive anions in an aqueous (CH3CN-H2O) medium. BMB-1 showed a hypsochromic shift (blue shift) with addition of CN- and F- ions in absorption studies. The lower detection level of CN- and F- ions is 1.37 × 10-9 and 1.75 × 10-9 M, resp. The BMB-1 binding mechanism is based on the nucleophilic addition of CN- and F- ions in the internal charge transfer transition of bithio moiety to the boranylmesitylene unit, and the color changes were observed under UV light. This result is further confirmed by Fourier transform IR spectroscopy, mass spectrometry and d. functional theory calculations Also, the BMB-1 probe is found to be a good adsorbent for the removal of F- ions in real water samples using the adsorption technique.
