New Highly Selective Colorimetric and Ratiometric Anion Receptor for Detecting Fluoride Ions

Abstract

F− detection: Two new polydentate conjugate molecules (1 and 2) as colorimetric receptors for detecting F− have been synthesized and found to have high fluorescent selectivity for detecting F−. In particular, receptor 1 has a more rigid structure without conformational flexibity that can be used as a ratiometric receptor of F−.
