| Abstract |
We report novel triarylboron-based fluorescent chemosensors for fluoride anion, CzmBT and CzpBT, where ortho-carbazoyl-donor and triazine-acceptor luminophores are attached to the meta- or para-position of the phenylene ring of triarylboron. To distinctly investigate fluoride binding behavior of these neutral compounds, X-ray single crystal structures of their fluoride adducts were also chracterized, showing 1:1 binding between triarylboron and fluoride anion. Whereas CzmBT and CzpBT fluoresce at 561 nm and 486 nm in THF, respectively, the emission spectra are either ratiometrically changed with a gradual hypsochromic shift (CzmBT) or gradually quenched (CzpBT) upon addition of fluoride anion, allowing the detection of fluoride anion. Details of synthesis and photophysical and fluoride binding properties will be presented. |
