文摘

A new calix[4]arene-based sensors containing fluorenone moieties for F− is introduced. Its binding properties were investigated by absorption, fluorescence and NMR spectroscopy. It has high affinity (Ka = 1.18 × 10+6 M−1) and selectivity for F−. The detection limit of sensor towards F− is 3.20 × 10−8 M.
