A new class of functionalized calix[4]arenes as neutral receptors for colorimetric detection offluoride ions

Abstract

A new class of functionalized calix[4]arenes have been synthesized and evaluated for colorimetric detection of fluoride ions. The molecular receptor 4b selectively recognizes fluoride ions via H-bonds and subsequent deprotonation to elicit a distinct colour change from yellow to dark purple.
