A calixarene–BODIPY fluorescent sensor for selective Fe3+ detection in environmental water samples: insights into static and dynamic quenching mechanisms
A calix[4]arene-functionalized BODIPY fluorescent probe (Calix-BODIPY) was developed for the selective detection of Fe3+ ions in aqueous media for the first time. The integration of a calixarene recognition unit with a BODIPY fluorophore enabled efficient fluorescence signal transduction, resulting in a rapid “turn-off...
