Selective fluoride ion sensing using novel quinoline chemosensor insights into kinetics and molecular logic gate functions.

CQHC, a novel colorimetric fluorescent sensor, developed for the selective sensing of ions and well characterised, including SC-XRD. It demonstrated selective sensing for Co, Zn, Hg and F using absorbance titration at 420 nm, 446 nm and the binding constants estimated follows the order F > Co > Hg > Zn. On light of this, molecular logic gate was built for CQHC's selective multi-ion detection.
