Abstract
Phoxim, is a common pollutant present in the environment and food chains, which exhibits irreversible neurotoxicity and poses a grave threat to food security. Herein, a novel 8-hydroxyquinoline-pillar[5]arene was synthesized and applied in a fluorometric chemosensor to detect phoxim. The fluorometric chemosensor shows great selectivity/sensitivity to phoxim, which is due to the formation of inclusion complex between 8-hydroxyquinoline-pillar[5]arene host and phoxim guest. Besides, the presence of other common pesticides did not disturb the responsivity of this chemosensor. This work provided a reliable and rapid method for detecting the pesticide residue.
